with a lot of reading i have gotten to the point of where i can keep track of scores for two players and start and stop the play clock. however i cannot figure out where to put the command to stop the clock and sound a buzzer once the clock hits zero. i have placed the if statement at the end of the loop and many other different places within the code. however everytime the clock hits zero it just keeps counting down and show -1,-2,-3 etc etc. Anyone have any hints as to where im going wrong. thanks
oh and i know i can increase a counter by one with a button press. example buttoncounter++. but is there a way to increase it by 10 or even 100. i have tried. buttoncounter + 10 and it does not work.
Thanks again
