Scripting Error

I am trying to make a weapon sway script, but when I attach it to the weapon it gives of an error. I know it is one line of the code that has the issue

        MouseY = Mathf.Clamp(MouseY, -15, ____, 15);

I want to change the rotation of only 2 axis but it gives off the error

Assets\WeaponSway.cs(21,43): error CS0103: The name ‘____’ does not exist in the current context
EDIT: Fixed it
