Unity Add Shooting Controller - easy one

Question

I am very new to unity, and still learning how to create games and edit scripts, so this will probably be easy for anyone to answer. I don't really know what you want to see.

I have a script for using the left mouse button to fire. I want to add one for the right mouse button.

What I've done:

I copied the script that calls the objects and changed the name to Fires. I added the controller button I copied the same lines for Fire (original) in the Input manager script. changed the names to Fires.

The problem: pressing right mouse button doesn't do anything. If I use the Input Manager to call Fires, it works, but not when I press the button. I'm missing something, but I'm not sure what.

Any help would be appreciated.
