It is difficult to tell without seeing the code. Can you copy the
UserForm/Control code and post it for us to look at.

Inside a module I call a userform with a listbox from which someone have
to chose an Item.
From my understanding if I put "UserForm.show Modal" the program must stop
until someone click on one Item inside the ListBox & confirme the
validation with CommandButton, but instead the program show the listbox
fill correctly but don't stop to wait for the interaction of the user &
continues to run until the end of the module.
What I do wrong?
Thank you for your help.
