Eric, Tony, and Mark,
Thanks so much for all your help. I was using the << item >> var because
it saw it somewhere and it worked for what I was using that was a bit
different. I have changed that code to not use the variable attribute for
that listWidget and re-coded a few things and it is working well, and I
like the dynamics of it. Thanks so much for that !!
And thanks so much for the other use case where I can bring in the
addsuffix and prefix type operators, because I need that too!
