You forgot i++;, so its just an infinite loop.

True, but also, that loop would record the same values about 90 times (+/- 1). Better would be to have the record code in the main program and just do 2 if's (if button and i<90) so that it records what you do. Then in the replay code, use for(i=0, i<90, i++) {...} so that it will loop though it that number of times. This makes changing your code easier and easier to read.

But, I guess if the compiler didn't complain, it's alright.

A better way would be "pwm01=pwm02=127;" becuase pwm02 then is 127, afterword, pwm01 would be set equal to pwm02, making pwm01 127. You could check the values with a debugger or have some visual output, but I don't think "pwm01,pwm02=127" does what you think it does, but it isn't the cause of the problem.
