>I built a function that passes parameters to it and basically builds up a listbox with choices. How can I call the function and have the program stop at the function call and wait for a selection or selections and OK button being pushed before proceeding without putting the remaining code under the button while allowing the user to select from the listbox?

Presumably you're putting the listbox in a form. Make the form modal.
