Layers and Form Fields

Hello,

I've created a form with layers and now I'm trying to add a validation script that will show only certain form fields at a time contingent upon when the name of the layer is selected from a drop-down box. This script is something one of my coworkers put together for another form to be used as a template.

I've been tasked with creating this same function for similar forms. I have created another form with layers and fields and I have pasted the script I edited into the validation box for the drop-down field that contains the names of the layers as Options but it's not working.

How do I make the script in the drop-down box pull the layers when they are selected from the drop-down box? I'm sure I have the names of the layers and drop down option correct in the script, I'm just not sure I'm applying the script correctly.

I will say that in the original form template there is only one set of form fields where certain fields are hidden/visible as needed. In the form I created, it was necessary to create several sets of form fields where each set is to be hidden/visible at a time due to the location and size of the tables in my layers.
