Fixed_update not being run on certian scripts (Solved)

i’m switching the physics in my game to use the fixed update system, however, the fixed_update function in one of my scripts is not being called, but in another script file it is being called with no problems.
what is causing this? the other functions work just fine.

Is it a GUI script or a GO script?

GO script

nevermind, it was caused by recklessly copy pasting the code into the other script and leaving a misplaced end
