If I'm not mistaken, that's more for a time elapse scenario? I'm not sure how I can make the changes from that to an ON/OFF timer.

I made a mock up of what a user manual might look like so as to give a better idea of what I'm trying to achieve - http://sparky3489.webs.com/Timer8.pdf

Everything works EXCEPT the few bugs I have in the many possibilities a user can select for ON/OFF times.

This is the entire project start to finish - http://sparky3489.webs.com/pcinterfaceproject.htm
