I've read several of the post on doing this but can't seem to get mine to work. This is the in the same Module called BREAKDOWNS. I am attempting to populate the date is one field with data from another. The fields are in the same module, however, one of them is a lookup field to another module. Here's what I have.
Field1: Production Title (Lookup field to Module PROJECTS)
Field2: Production Title Catch (Single Field)
Field3: Production Title Calc (Formula Field to do the calculations)
I'd like to add the data from Production Title field to Production Title Catch Field after user updates Production Title field.
