Wouldn't that always be true if you input 1 - 4 ? Can you elaborate on that a little? thanks.

I put that in to verify that the selection was a number in the range 1 - 4.	[reply]

Got it. When I first looked at it, I was thinking the do..until loop was still controlling the 'outer' loop..like in my original code. Now I see that you moved that to a while loop.	[reply]
