Hi there.
I'm trying to make a menu in an LCD, this menu has 2 buttons, the first one is a selection button and the other one is an "OK" button, what I want is to select a song, and after that when I press "OK", i'll get, on the buzzer, a melody played by the buzzer depending on which menu I selected of course.
What I need is a synchronization between the menu I'm actually choosing and the song to be played, what I mean by that is, in my menu, the first option, for example, Queen, must actually play me a Queen song and not any of the other melodies, what I thought might be a good idea is, to make a counter, which will count everytime I press the selection button, I have 4 different bands in my menu, so the counter will go 0 1 2 3 0 1 2 3 0 and therefore, when I'll press OK, the program will check the counter, lets suppose for instance its equal to 2 and will launch melody 2.
I know this may seem long and pretty basic, but I'm totally new to Arduino & programming so I'm trying to apply basic ideas.
Now, for the program, here is what I wrote :

}
The result is, the menu is working fine, but when for example on the monitor, the counter is equal to zero, when I press the OK button, the "imperial" song doesnt work. The led on the arduino stops blinking which normally means there is a change of voltage from high to low when pressing the OK button, but the buzzer doesnt play the song...
