My mistake. It's Radio Repairs::Store Number and Defaults::Store Number. The purpose is for multiple stores to use this file and to be able to set their default values, and have them automatically fill into the form with one click. I have a value list with store identifiers. The value in Defaults::Store Number must be from said value list. When the value from Defaults::Store Number is entered into Radio Repairs::Store Number, the contact name, contact email, and model will automatically populate from the values found in Defaults::Model etc (this I have working using calculated values). So what I'm trying to achieve is a script that will lookup the value from Defaults::Store Number and populate it into Radio Repairs::Store Number. So, I can't set it as an auto-enter because it will differ from store to store.
Please excuse my lack of explanation/providing details. I'm trying really hard and I appreciate your help. There's so much terminology I don't yet know.
