Led vu meter with midi

Projects Programming
1

hi, i am trying to make a VUmeter, with 2 states. (vumeter) and (vumeter_main)
i need by default to be active the (vumeter) and when i press the button to active (vumeter_main) and cancel the (vumeter) and when press it again to stop the one and start the other..
but unfortunately i cant manage it.. lot of error.

if(VUbuttonvaleu !=0){      //I DONT KNOW WHAT TO DO NEXT SO WHEN BUTTON IS PRESS IT WILL ACTIVATE (VUmeter)
                            //  and when press again it will deactivate VUmeter and activate 
}
  
}

#define SHIFTPWM_NOSPI
const int ShiftPWM_dataPin = 11;
const int ShiftPWM_clockPin = 12; 

const bool ShiftPWM_invertOutputs = false;
const bool ShiftPWM_balanceLoad = false;
