If the exception is pointing to like 11 then you have not set imf in the inspector.

in the inspector in Unity do you have a object linked to the field imf? if you do not then that is your problem. Your script is fine. The problem is that imf is not assigned in your scene.

Ryuuguu is probably right, but in future you should post the entire exception, which will tell you the line number where the error occurs.
