SWEP self is nil?

[PerkyMcRibs]

I have this code in a SWEP.

For whatever reason, the code won't get the table I have set.

The error I get:

Change SWEP to self inside of a meta function. Also, you should really just restructure your code to determine the size at render time instead of updating the table every time.

Nah that's not it.

I'm trying right now but I think what the problem is, is when I set the right and left hand "HB" and "Group".

I'm not actually checking if it is the right or left bone. Something screws up there

Yep, that was it. On to the next error.

Oh my god, what are you even trying to code, please, structure your code correctly, i'm impressed that the code even runs in gmod, or even try

Stop creating methods inside another methods please

It might not be your biggest problem but it will still stop your code from working just the same.a
