Validation message not showing

I have a page which has 15 Validation boxes working OK

I decided to add one more.
All validations work OK except this last one I am trying to apply.
For some reason this last validation will not show the error message.
The code for this is
<?php
if (ValidatedField('boatsInsert_000','boatsInsert_000')) {
if ((strpos((",".ValidatedField("boatsInsert_000","boatsInsert_000").","), "," . "16" . ",") !== false || "16" == "")) {
if (!(false)) {
?>
Measure Unit Required
<?php //WAFV_Conditional boats_Insert.php boatsInsert_000(16:)
}
}
}?>

Can anyone see where this may be gong wrong please?

Many Thanks

John

no way to tell why the message would not show without seeing the validation code that should trigger it.

please send a copy of the full page in a zip archive.

Sorry I thought the above code was the validation code.

I am attaching the zip as suggested.

Thank you

John

the last validation was added to a seperate server validation behaivor instance.

instead of adding a new server validation instance for the new validation, you should edit the existing one and add it the list of validations to perform.

open the server behaviors panel (window -> Server behaviors)

you will see 2 instances of the server validation behavior. delete the second one, then edit the first one (double click it) to add the new validation.

I have made a note That there must be one only WA Server Validation per file.

Many thanks

John
