What is the best way to end an Add to Variable from empty stored variables that I am adding to. Copy from source successfully for Data1, Data2, and Data3 is Empty (copy from source loop will end, now I want to add to variables only to datafields that have data). Add to Variable - [Prefix]Data1,[Prefix]Data2,[Prefix]Data3 (I want to end add to variable if Data1, Data2, Data3 are empty.) I've tried all kinds of loops and conditions with no success. I ran into the same issue on the demo version of Version 3.

Usually you use an If Condition if empty to check if an data field is empty an act accordingly. In version 3 there is an new action called Validate Data that can also check on empty values and jump to a label in such an condition. You can also nest If condition is empty variables if that is what you mean. See the attached script. Tijn
