Well I thought I had this last part all figured out-- my other forms load
this way with no trouble whatsoever, but not this latest one....
argh!!!

As far as I can tell, in order to call a form from the xlam-- once the xml
code is in place-- is to create another macro, in a module, within the xlam
file.

sub userform1(control as IRibbonControl)
userform.show
end sub

this has worked on 5 other user forms that I have, but not this one.
I've quadruple checked and the modules, and forms are in place. Thankfully,
nothing has disappeared here-- that I can tell.

Would someone please explain to me how to get a user form to start up?

Thank you.
Best.
