Cant get values from return [closed]

I give up and don't understand how to fix the code, I ask for help. Return does not return anything in my case. In the console, it really gives a result, but it is not needed in it. How do I make a working code out of this? All variables are taken from unity. To understand, the condition of such a "tool moves 3 pins depending on the values of the parameters of the tool (tools - 3)", I shortened as much as I could and reached the return, but there was no response from him.

 private int PinsOnInstrumentClick(int param, int pin) {    pin += param;    if ((param > 0 && pin <= 10) || (param < 0 && pin >= 0))    {        return  pin;    }    else    {        return 0;    }   } private void PinsOnDrillClick() {     PinsOnInstrumentClick(drillParam1, pin1);     PinsOnInstrumentClick(drillParam2, pin2);     PinsOnInstrumentClick(drillParam3, pin3); } private void PinsOnHammerClick() {    PinsOnInstrumentClick(hammerParam1, pin1);    PinsOnInstrumentClick(hammerParam2, pin2);    PinsOnInstrumentClick(hammerParam3, pin3); } private void PinsOnLockpickClick() {    PinsOnInstrumentClick(lockpickParam1, pin1);    PinsOnInstrumentClick(lockpickParam2, pin2);    PinsOnInstrumentClick(lockpickParam3, pin3); } public void DrillClick() {    PinsOnDrillClick();    GameWin(); } public void HammerClick() {    PinsOnHammerClick();    GameWin(); } public void LockpickClick() {    PinsOnLockpickClick();    GameWin(); }
