Hello again

 How stupid can one be? I have just seen the light (Haleluja). This thingie
will never work, if i have to use two of the timers at one time. As i am
clearing timr1, timr2 will never get incremented..... I saw this when i was
laying in my bed this morning, and was just about to get out of it....
Funny places where the light shows up.. hehe...

anyway, thanks to everyone that has (or is) using theire time on this
subject... Also thanks to all the people that helped out on my last
question....

- Thomas
