What's wrong with my SQL syntax?

Hello,

I have written the following SQL query to find the local region:
$lreg = mysql_query("SELECT lat,lng,maxzl,icon FROM regions WHERE locations['reg_id']");

and i'm using the following to process the results:
// this displays the local Regional marker
while ($row=mysql_fetch_object($lreg)){
      echo '<reg_local lat="'.$row['lat'].'" lng="'.$row['lng'].'" maxzl="'.$row['maxzl'].'" icon="arrow"/>';
}

Can't for the life of me see what's wrong but Firebug reports the following regarding the line beginning 'While':
:  mysql_fetch_object(): supplied argument is not a valid MySQL result resource

You can see this here (line 66):

Any tips appreciated

you did open a connection, did you?
also, try to get the actual mysql error:

$lreg = mysql_query("SELECT lat,lng,maxzl,icon FROM regions WHERE {locations['reg_id']} = id") or die(mysql_error());

  Your WHERE clause is typed in a wrong way , you are not making any kind of comparisions on there it should be something like ;

   WHERE locations['reg_id'] = "Some number" ;

hieloCommented:
your where clause is missing "fieldName=".  Do you have a field named "reg_id"? If so, try:
$lreg = mysql_query("SELECT lat,lng,maxzl,icon FROM regions WHERE reg_id = {locations['reg_id']}");

Sorry for the delay in getting back to you...

I have changed the WHERE clause to:
$lreg = mysql_query("SELECT lat,lng,maxzl,icon FROM regions WHERE {locations['reg_id']} = id");

and i have tried using:
mysql_fetch_array
mysql_fetch_assoc
mysql_fetch_object

None of these have worked.

 What do you suppose i try next?

What is this:
{locations['reg_id']}

Most likely you meant:
{$locations['reg_id']}
$lreg = mysql_query("SELECT lat,lng,maxzl,icon FROM regions WHERE {$locations['reg_id']} = id");

When this MySQL query is included in my read file it causes Firebug to report this problem:

handleErrors is not defined
http://www.globexposure.net/index_dubious.php
Line 291

I have created a development version of the site & read file, where you can see this:

www.globexposure.net/index_dubious.php

Obviously not sure why this is happening
