Kyzer, he's probably thinking the ULX feature.
Remember, most who come here don't know Lua. (And of those that don't, even fewer want or care to learn)
Glitch,
ULX only allows admins to pick players up.
99% of the time a player can pick another player up, its not ULX's fault, but a conflicting mod.
In the past, several other prop protect scripts broke the feature.
Also, make sure ou have ULX 3.11
