Colour correction help [Solved]

[squ1rrel]

Solution: Remember to tick the Enable box on the ui xD

Problem: The colorcorrectionui sliders have no effect when used in game
What I've done so far:

-Created a color_correction entity
-Ensured the fall off values were -1
-No look up table entered
-CC is enabled in adv options
-sv_cheats 1 enabled​

I don't know why the ui sliders have no effect in game. Any help greatly appreciated.
