Well, its not a code-specific problem, but here's an example...
if I use a webform to submit variables, via get, the url would be:
page.php?name=bob&town=london
so my php page would consist of code saying:
<?php
print "your name is $name";
print ("you live in $town";
?>
And nothing would show up! Quite simply, the variables would not be passed to the page - even via GET, instead of POST.
Any thoughts?
