Is an If...then... by cycle possible?

[Rivermaker]

Thanks David!

So I should learn how to set up a global variable and then I should be
able to use an If...Then...else... command. Doesn't sound like it's
too hard. I will follow your advice and come back here if I get stuck.
Thanks for your time and assistance.

Mike
