Button Popup if no selection made

[venkatg6759]

Hello Everyone ,

I have 3 list boxes in one tab and a button which takes you to another tab. I have to make button work only after making selection from atleast one list box or else it should show me a popup.

Is there a way to solve this .

The button should function only after making atleast one selection.

Use this as variable definition:

=GetSelectedCount(F1) xor GetSelectedCount(F3)
