physic gun help

So im using ulx and other players can use their physic gun to pick each other up and i have it disabled but i cant pick people up and other admins can pick each other up help please im not sure what the problem is

You can change the permissions / who can pickup who with these two hooks. Do a search in the ULX directory and it should come up with something. Modify the files.
PhysgunPickup
PhysgunDrop

where is the directory?
