I am quite new to programming so please be patient 
I am making a timer bomb simulator for a puzzle box project. The goal is to cut the correct 2 (of 5) wires based on previous hints. The program is working just fine. However, when i try to introduce a buzzer and make some beeps, the compiler just refuses to accept. (line 57) I tried the tone function in another scetch and that worked. What am I doing wrong?
