I've never played the game myself, though when in battle mode I believe you have to press Z. However, in Mettaton's default form, this will not work.

Shooting is only usefull when he attacks you in his EX form, which ranges from boxes and bombs, disco balls, etc.

This function also must be used when defeating him by destroying his legs, during one of the points where he exposes his SOUL (At least that's what some people think this heart is), and you can shoot it.

I hope this helped!
