Hi, I'm sure you'll get some good help here. Can we take a step back and can you describe, in the most non-programmy/tabley/fieldy terms what you're trying to accomplish. For example, one end goal might be something like "I'd like to create a PDF that lists all the books that came out in the year x"
Then with a button I want to export to excel and fill Virtual List with my Title contents.
The reason I ask is because it's not clear (to me at least) what the end result should be. Also, Virtual List has strong idiomatic meaning in the FileMaker world and it's not 100% clear here whether it's being used "non-traditionally" in your system.
I apologize if you felt you were being very clear and I'm just not understanding.
You can likely accomplish this without VirtualList. Try:
Export Records script step.
Select the fields you want to export selected in the "Specify Export Order" dialog, and drag them into the order you want. This can also include fields from related tables.
