most likely, validatuion is failing,
To see if this is the case, change the following code:
if ($WAFV_Errors != "") {
PostResult($WAFV_Redirect,$WAFV_Errors,"apply");
}
to:
if ($WAFV_Errors != "") {
die($WAFV_Errors);
PostResult($WAFV_Redirect,$WAFV_Errors,"apply");
}
if validation fails, it will write a comma separated list of numbers to the screen, post the results back with your reply.
