Data Rule Kinetic

I’m trying to set the value of a Data View column from a different data view column. What is the correct format to use in the Value field? It seems to just take the string literal of whatever I type in here.

Just had to put it out in the Universe.

Change Value/Field to Field

What if you need to create a string as the ending action value? - i.e. orderdtl.partno & " - " & orderdtl.description

Every syntax i try comes out like Zach’s - completely literal

Can that be done with a data rule? Is there a better way to do it?
