Have updateRow function chose field to update dynamically

It’s still possible you’re getting an object instead of a string. Could you post the assignment statement where you get the field names?

I think I have done - or attempted - this somewhere, but I can’t recall which of a couple hundred pages. We are reviewing those one by one for our v9.5 to v11.1 upgrade, however, so I’ll look for it. I can’t give you a timeframe however. Let’s hope you get a quicker answer from someone else.
