Unable to control Pitch on camera.

Hi

I am trying to set up a system where, when I press the Left Mouse Key the camera switches from the characters camera to a camera on my weapon, the problem i’m having is when i do this I can only move the camera in the Yaw direction (left.right) but not the Pitch (up/Down) in the weapons view it does seem to move in Pitch but only becuse of the animation of the character, as aposed to me moving the Mouse.

Thanks for any Help.
