Flash as2 Information needed on using Timers

1

I have a power meter called powerMeter_mc and a test button called test_btn. I have a dynamic text field called myDisplay_txt. I tweened the powerMeter to go up and down. I made the text field into a timer that goes up to 100 and down to 0 in sync with the powerMeter. What I can’t figure out is, when I press the stop button, to stop the number on the current number and stop the progress bar in its current place? Thanks all!
