Okay Jason, I'm lost. I did the following:
I created a page called insert_test.php. I added a form with only one field 'first name'. I applied the WA Insert Record behaviour. I then created a WA Server Validation - a 'require' validation. This created a folder in the bindings panel called 'WA Validated Entries'. I dragged the only field in this folder over to the form field name 'first name' to bind it, and this is what appears in the field:
<?php echo(ValidatedField("inserttest_365","f_name")) ?>
It's a lot different than:
<?php echo((isset($_GET["invalid"])?ValidatedField("usersinsert","UserFirstName"):"")); ?>
The isset part seems to be missing. What am I doing that's incorrect?
