I'll can try calling. But....here's an example part no. for it to auto populate: ST0005. I only care about the function named changeAllProdSelections(). If there's something already there, and you enter nothing, it leaves what was there. That's fine. If you input something that doesn't exist, make it do absolutely nothing (or just don't run that function) including not changing what was there. Just nothing.
Once I see that, I can probably fix the rest. Thanks.
