Funny this title looks very similar.  Yes it is.  After typing the question I figured that I should break the question up, as they were different.

I'm using the scriptaculous library for my ajax stuff and I would like to do more then one field on the page, however the snippet that I have been using was only written for one field.  I would like to make it so that I could call functions rather then pages so doesnt anyone have a clue on how to do that?  I've tried <?=acQuery()?> but nothing.

<input type="text" id="rep" name="_field" tabindex="1" value="">
<input  type="hidden" name="field" value="-1">
<div id="autocomplete_choices" class="autocomplete"></div>
<script type="text/javascript" language="javascript">
                    new Ajax.Autocompleter('rep','autocomplete_choices','acQuery.php', {paramName: "q",minChars: 1, afterUpdateElement: updateHidden });
</script>

If you want to use more fields, just copy the code, like so:
<input type="text" id="rep" name="_field" tabindex="1" value="">
<input  type="hidden" name="field" value="-1">
<div id="autocomplete_choices" class="autocomplete"></div>
<script type="text/javascript" language="javascript">
                 new Ajax.Autocompleter('rep','autocomplete_choices','acQuery.php', {paramName: "q",minChars: 1, afterUpdateElement: updateHidden });
</script>
<input type="text" id="rep2" name="_field2" tabindex="1" value="">
<input  type="hidden" name="field2" value="-1">
<div id="autocomplete_choices2" class="autocomplete"></div>
<script type="text/javascript" language="javascript">
                 new Ajax.Autocompleter('rep2','autocomplete_choices2','acQuery.php', {paramName: "q",minChars: 1, afterUpdateElement: updateHidden });
</script>

If you want to call functions instead of the whole php page, use something like this in your php page:

// Grap command/function to execute (default if not set or set with bogus value)
$valid_commands('function1', 'function2');
$command = (array_key_exists('cmd', $_REQUEST) ? $_REQUEST['cmd'] : 'function1');      
if (in_array($command, $valid_commands))
                $content = $command();
        else
                $content = function1();

and then use your script like so:
<input type="text" id="rep" name="_field" tabindex="1" value="">
<input  type="hidden" name="field" value="-1">
<div id="autocomplete_choices" class="autocomplete"></div>
<script type="text/javascript" language="javascript">
                 new Ajax.Autocompleter('rep','autocomplete_choices','acQuery.php?cmd=function1', {paramName: "q",minChars: 1, afterUpdateElement: updateHidden });
</script>
