You need to add “ACollidingPawn::” in between “void” and “DebugStartGrowing” like so (in your .cpp):

    void ACollidingPawn::DebugStartGrowing(){
    UE_LOG(LogTemp, Warning, TEXT("Pressed!!!"));
    }

Same is true for the second function “DebugStopGrowing”. It is also missing the “ACollidingPawn::” prefix.
And make sure that the two functions are properly defined in your .h file too.
