Thanks for the tips Dan, I thought the DRY thing could not be right. Not sure I understand tho - I originally made the form with just the inner Meta class definition - do you do that and then override things that need to change (e.g. where I want to use a longer TextInput widget or whatever.
Things worked fine until I changed to the above form definition so that I could make mods to the default output. re "client = forms.ModelChoiceField(User.objects.all())", that is the line I mentioned above that I commented out because I suspected it too. I tried your change, still not working Here is the traceback. Thanks Dan and Andrew, listening while I am being so verbose, but I wanted to convey as much info as possible. I am learning django and python together, and it gets to be pretty boggling sometimes, although it is the most fun developing I have had in years. I appreciate you taking your time looking at this.
