One button for multi function

i trying add 1 button multi function built aquerium light control string of 1w rgb led's.each channel of rgb controlled pot , works except want use 1 button click exit loop set defined pwm value led's.my problem think sketch counting button clicks when 4 turns off led's pulsing on/off at  button count 1 - 3.any guidance appreciated.incidentally code running on attiny44.the code messy works fine except switch count function.

 while (switchcounter == 3  ) {
  option_3 ();
  }
if switchcounter equals 3 how ever change value , exit while loop ?
