GTA Style Aiming

Hello,

So I have a simple start to a GTA game I am making. I have a good player and I have a smooth follow camera behind him and the player has a MouseLook script moving its x axis which spins the player according to the mouse. When I click the left mouse button to aim it has a simple zoom script where all it does it zoom a little. The problem I am having is that when I aim I can't function the Y axis to move at all, it only works on the x axis. I thought about it a little and if I do get it working on the Y axis I will also need the player to face or follow the mouse on the Y axis so it looks like it is looking at it. If anybody could help that would be great.

Thanks
