help with suit code

[LuciouS]

so i used mito's armors as a base from the workshop and i got to this

and i simply dont understand why the hook for the drop dosent seem to work? it used to work and suddenly stopped then all of a sudden it works only when i click save again on the lua and then all of a sudden again after a restart or so it dosent anymore? im so confused i simply want people to be able to do /unequip and wait 8 seconds and the suit drops infront of them to pick it up with their inventory, what am i doing wrong?

You should use hook.Add.
