Somehow your recordset is out of sync. It had on line 39 the parameter defined: $paramrandomstring_rsVerify
But then in the recordset it was referred to as: $paramrandomString_rsVerify
The case sensitivity. It probably didn't update properly when you tried to change it.
The resend confirmation link worked for me from the update page, so I'm not sure what the issue was with that, but it appears to be resolved.
