Validation show if behavior error - changes to code that is not marked as editable

DWCS3 error msg after completing page 72 of "Validation Toolkit Recipies", setting server behavior -> validation toolkit

->validation show if.

After configuraiton is set and you click on the "ok" button, the following error pops-up. This only happens with the first

elemement. There is no code placed outside of the editable region on the page that I can find. All of the pages are from a common template. Older pages which had validation set and were working are now showing a red "!" warning beside each "validation show if" behavior. Please confirm what I should do to correct the problem. I am setting up validation on 9 new forms with 7 completed previously completed and working (now with error warning). Is it simple or do I need to open a ticket?

You have made changes to code that is not marked as editable. If you retain those changes, they will be lost the next time you apply a template update to this file. Do you want to retain the chages until then?


THE FOLLOWING PHP CODE BLOCK IS ADDED INSIDE THE FORM TABLE:
<?php
if (ValidatedField('memberRegistration1','memberRegistration1')) {
if ((strpos((",".ValidatedField("memberRegistration1","memberRegistration1").","), "," . "" . ",") !== false || "" == "")) {
if (!(false)) {
?>
* Please correct the error(s) indicated.
<?php //WAFV_Conditional member_Registration1.php memberRegistration1( :)
}
}
