I was just going to point you there. I would set it to 8.1, that's what
we do with all our forms. Check what version your client is using.At
some point people do need to upgrade and the software is free. Version 8
is quite old now. And there were a lot of changes between version 6 and
8.Check the Warnings log (Window > Report) to make sure things are
compatible, it will tell you if you've used features that won't work
with your target version.
