Hi Dave,

The answer is actually very simple:
Your desired line:
param1=abcd&agency_id=<?php echo $LTON; ?>&param2=dex

is not a legal url.

You should urlencode all paramvalues before using them in an URL.

So try something like:
$theURL = "?param1=".urlencode("abcd");
// not very usefull, but you should do it with values
// that possible contain difficult character.

$theURL .= "&agency_id=".urlencode("<?php echo $LTON; ?>");

$theURL .= "&param2=".urlencode("abc");


That should work.
Check your results by starting your script with:

<pre>
<? print_r($_GET); ?>
</pre>


It will spit out all name/value-pairs.

Good luck,
