How do you make a time bomb beeper

Help Me I'm Dying

o I'm working on a game where there is a time bomb, the bomb is set to go off after one minute. I want to add a feature where the bomb beeps and it gets faster and faster building up suspense before the explosion. I managed to make something but it isn't working correctly. The script below works but only on 10 second intervals. Meaning it only beeps every ten seconds, and all the other while loops are ignored.

If you can help me figure out the problem that would be great. Thanks in advance!
