I just went through my Dreamweaver preferences, and don't see any way to select binary vs. ascii. I assume ascii is default, but I'm not sure. The reason it isn't UTF8 is because an earlier error either in this thread or another was due to php and some UTF8 combination error. So I had to switch it off.
Well I do notice that your delete operation forwards to:
$WA_redirectURL = "drequests_results.php?Orderkey=".((isset($_POST["WADADeleteRecordID"]))?$_POST["WADADeleteRecordID"]:"") ."";
and I do not see a value of Orderkey referenced as a GET variable anywhere else. I do see a Dealer_ID referenced as a GET variable in the recordset.
Is your delete function redirect GET incorrect, because if the GET is incorrect, that's what you GET, correct? GET it?
