SOLVED
I finally figured out the step I hadn't taken. I had to add an else statement at the end. I can't remember seeing that in the instructions, but when I look back it seems logical.
In case anybody else is looking, I ended up with this code...
if ($WAFV_Errors != "") {
PostResult($WAFV_Redirect,$WAFV_Errors,"regfull_746");
}
//This is the part I added ( I could have added code in here too...
else {
header("Location: new page to go to");
}
//
}
Thank you Ray, your comments helped me solve this. thanks for a great product!
