Unique validation not working when inserting record - DataBridge latest Beta

Hi there Ray, I have the latest DataBridge Beta RC 2.1 installed in Dreamweaver CC 2018, Windows 10 64 bits, I'm using WAMPSERVER 3.1

Now, everything else is working so far, smoothly! Maybe is my problem implementing the validation.

Thing is this, I have a php page with a form that inserts a record, in the landing page after the insertion I have the server validations applied to check for uniqueness on two of the form fields("rolloid" and "codigo").
Validations were working until I inserted the Insert Record behavior in the landing page, so it probably has to do with it.
Maybe a change in the order these scripts are loaded? This is still in my localhost, not online.

I'm attaching the page rolls.php where the validations are applied (as shown in the video tutorial) and rolls-add.php that is where the insertion form is.

I'm only checking for uniqueness in two values, one is the form field name="rolloid" and the other one is the form field name="codigo", both at the very top of the form named "roll" in the rolls-add.php page

Maybe you can see what's wrong. Thanks much!

Hi Ray, I just found the solution on an answer you gave to another user on a similar situation. I got it to work now!
In case someone else needs to know here's what happened. The server validation tutorial shows an example where the validations are applied on the confirm page, coming from a checkout page with the form to validate.
In this case, I followed Ray's advice that goes like this and has to do with the order of the functions and what page to be applied to:
"Server Validation, File Upload, and Insert Record server behaviors must all be applied to the same page, in that order, and that page should be the action page of the form."
So, I moved my check unique database value server validations from my landing page to the page that has the form fields I wanted to validate in the suggested order. All worked smoothly.
Maybe is on my particular case, but it worked for me, again I was only checking for two values against the database, nothing else. And I had a file upload as well. All worked perfectly following the order and moving all validations to the page with the form to be validated, also.
Action attribute on the form was set to empty and all validations were set to perform on form submit or button clicked. That's it.
Hope it helps others!
