Help-me with stop on tick update after a if statement

All i want is the player cannot equip until he have the advancement and it work very well! But even when he get it (the advancement) still desequipping :\
A fun thing that let me crazy is the message stop sending when the player get the advancement but the rest of the "do" script not.
