What about using the tick() function? Something like:

Code:
int thisBar, ticks;

funtion tick() {
   if (Bar == thisBar) {
      ticks += 1;
   else { 
      thisBar = Bar; //increment thisBar to start counting a new bar
      ticks = 0; //start counting ticks from zero again
   }
}


I haven't run this, but it should work.
