Lua Error with Spiderman Gun SWEP

[GodzBro]

I get this error:

Any help is greatly appreciated.

local self.dt = .....

You don't use local with self.xxx
Either
self.dt = ...
or
local dt = ...

[c👌de_g🎷]

Try using just self.dt = -1 on line 119; like Wh1t3 said, either local dt or self.dt

Worked, thanks.
