Hello Forum and thanks in advance.
I have a fairly straightforward UserForm with 4 listboxes and 4 option textboxes (the textboxes do not need to be a part of the validation I'm needing). I then have a command button that I want to be enabled ONLY if ANY of the 4 Listboxes have a selection. I've tried the "Change" event code below and it works upon the first selection of any listbox item. However, if the user de-selects all selections in the listboxes (i.e. they are all unchecked), the command button remains enabled. I need the validation logic to enable/disable the button to persist as long as the user has the form open and if there is not a selection in ANY of the listboxes. The reason being is that if they click the command button it will update the cells in the worksheet, which if empty may overwrite previous work completed with blank cells.
I'm not necessarily tied to this approach, so other ideas are welcome. Your collective expertise and input is greatly appreciated!
Thanks,
Chris
