Item Damaging

[oHeckGage]

I am trying to make items that give special effects when in your main hand. When the durability goes down, the skript stops working, as it thinks that the only thing it can do is... give it if the the sword/item has full durability. Is there any way to solve this? I have tried to make it so it repairs the item but when I try "repair player's held item" there are no errors but it doesn't work.

EDIT:

I forgot to put the code lmao:
