It works !

Melanie, I only had to make one change to get it to work...

While PulseInput=1:Wend
CounterA=0

I moved Wend to "after" CounterA=0...

While PulseInput=1
CounterA=0
Wend

Before I did that, LED would High anytime ButtonInput went Low.Now it only goes High during the "Time Window".
Works great and now I'll tweak it to suit my application and continue.

Thanks!!!
