   pwm06=0;
else {
   armcounter++;

It is VERY rare that you'll actually want to use a single = in an if, so watch out for that, and also be careful with your curly braces.

That said, I believe the code in its original form should have printf'd 15 over and over and over. Was it doing that, or just not printing anything?

Missing a = is an easy thing to do. It's one of those powerful, useful things that C/C++ lets you do, but isn't what you want most of the time.
