I must be missing something.  I have tried all day and still can't find a way to pass a javascript variable to an xajax function in the same page. What am I missing?

Help!
<?php
 
require_once("xajax/xajax_core/xajax.inc.php");
 
$xajax = new xajax();
$xajax->configure('javascript URI','xajax/');
 
$xajax->registerFunction("getll");
 
$xajax->processRequest();
 
 
function getll($longitude,$latitude){
//$lonquery=trim($formValues['longitude']);
//$latquery=trim($formValues['latitude']);
//$lonquery =  '-149.8375..-149.8373';
//$latquery =  '61.12851..61.12871';
$lonquery = $_GET['longitude'];
$latquery = $_GET['latitude'];
//$lonquery = $longitude;
//$latquery = $latitude;
 
require_once("FileMaker.php");
$fm = new FileMaker('Cama');
$findCommand =& $fm->newFindCommand('ASMLATLON');
$findCommand->addFindCriterion('LONNUM',$lonquery);
$findCommand->addFindCriterion('LATNUM',$latquery);
$result = $findCommand->execute();
$records = $result->getRecords();
 
$row = 0;
 
foreach ($records as $record) {
 
$taxid = $record->getField('TAXID_11');
$lat = $record->getField('LATNUM');
$lon =  $record->getField('LONNUM');
$row++;
}
 
 
$objResponse = new xajaxResponse();
$objResponse->script("row=$row;taxid = $taxid;alert('row=$row;taxid = $taxid');");
return $objResponse;
 
}
 
 
 
?>
 
<html><head><title>Xajax test</title>
<?php $xajax->printJavascript(); ?>
<script type="text/javascript">
<script>
x=0;
var taxid ;
var latitude = '61.12851..61.12871';
var longitude = '-149.8375..-149.8373';
<input type="text" size="24" name="longitude" value =  '-149.8375..-149.8373';>

There are some errors in your html. Try replacing it with the code below. To check that the lat/lon is transfered correctly, you can alert it like this:

$objResponse->script("row=$row;taxid = $taxid;alert('row=$row;taxid = $taxid,lon=$longitude,lat=$latitude');");

<html><head><title>Xajax test</title>
<?php $xajax->printJavascript(); ?>
<script type="text/javascript">
x=0;
var taxid ;
var latitude = '61.12851..61.12871';
var longitude = '-149.8375..-149.8373';
</script>
 
</head>
<body>
<form name = "searchdist">
 <input type="text" size="24" id="latitude" value =  '61.12851..61.12871' />
<input type="text" size="24" id="longitude" value =  '-149.8375..-149.8373' />
</form>
<div id="SomeElementId"></div>
 
<button onclick="xajax_getll(document.getElementById('latitude').value,document.getElementById('longitude').value);">test</button>
<button onclick="alert(taxid)">alert</button>
 
</body>

ep to write the variables to the fields then retireve them.

None of them, the parameters are transfered in the function call. They are defined here:

function getll($longitude,$latitude){

... and they are set here:

<button onclick="xajax_getll(document.getElementById('latitude').value,document.getElementById('longitude').value);">test</button>

"document.getElementById('latitude').value" fetches the value from the element with id=latitude.

Yes, if latitude and longitude are javascript variables, you can do like this:

<button onclick="xajax_getll(latitude,longitude);">test</button>

ok,  so how does the transfrred value get to :
$findCommand->addFindCriterion('LONNUM',$lonquery);


//$lonquery=trim($formValues['longitude']);
//$latquery=trim($formValues['latitude']);
//$lonquery =  '-149.8375..-149.8373';
//$latquery =  '61.12851..61.12871';
$lonquery = $_GET['longitude'];
$latquery = $_GET['latitude'];
//$lonquery = $longitude;
//$latquery = $latitude;

require_once("FileMaker.php");
$fm = new FileMaker('Cama');
$findCommand =& $fm->newFindCommand('ASMLATLON');
$findCommand->addFindCriterion('LONNUM',$lonquery);
$findCommand->addFindCriterion('LATNUM',$latquery);

The function definition also defines the input parameters:

function getll($longitude,$latitude){

...you can use them like this:

$findCommand->addFindCriterion('LONNUM',$longitude);
$findCommand->addFindCriterion('LATNUM',$latitude);

Now you have removed the parameters from line 13:

function getll(){

...it should be like this:

function getll($longitude,$latitude){

Except from that I can't see anything wrong.

It works for me. I don't have your Filemaker db, so I commented it out. Try doing the same, to elliminate the possibility of an error in that part of the code.
function getll($longitude,$latitude){
/*
require_once("FileMaker.php");
$fm = new FileMaker('Cama');
$findCommand =& $fm->newFindCommand('ASMLATLON');
$findCommand->addFindCriterion('LONNUM',$longitude);
$findCommand->addFindCriterion('LATNUM',$latitude);
$result = $findCommand->execute();
$records = $result->getRecords();
 
$row = 0;
 
foreach ($records as $record) {
 
$taxid = $record->getField('TAXID_11');
$lat = $record->getField('LATNUM');
$lon =  $record->getField('LONNUM');
$row++;
}
*/ 
$taxid = 123;
$row = 246;
 
$objResponse = new xajaxResponse();
$objResponse->script("row=$row;taxid = $taxid;alert('row=$row;taxid = $taxid');");
return $objResponse;
 
}

still get taxid undefined? works if i comment out my fm stuff. and include the taxid and row variable you put in.
<?php
require_once('xajax/xajax_core/xajax.inc.php');
 
$xajax = new xajax();

$findCommand->addFindCriterion('LATNUM',$latitude);
$result = $findCommand->execute();
$records = $result->getRecor3ds();
 
$row = 0;
 
foreach ($records as $record) {
 
$taxid = $record->getField('TAXID_11');
$lat = $record->getField('LATNUM');
$lon =  $record->getField('LONNUM');
$row++;
}
 
//$taxid = 123;
//$row = 246;

What value do you get for $row? if it is 0 (zero), it means the loop is not executed, i.e. no rows are found for these criteria in the db.

You said it worked if you commented out the filemaker stuff, and hardcode values for $row and $taxid? If so, the problem is obviously with the filemaker stuff. Create a separate test script with the filemaker stuff, and make sure that part works, before you move it back into the xajax script.
