That's because FireModes isn't initialized anywhere.

[Snowpaw]

How would I fix it?

[c👌de_g🎷]

In SWEP:Initialize(), before you insert stuff into the table, put

if not self.FireModes then self.FireModes = {} end

[Snowpaw]

Now getting this error:

[ERROR] addons/fas/lua/weapons/fas2_base/shared.lua:174: attempt to perform arithmetic on field 'CaseLength' (a nil value)
  1. CalculateEffectiveRange - addons/fas/lua/weapons/fas2_base/shared.lua:174
   2. unknown - addons/fas/lua/weapons/fas2_base/shared.lua:203

[c👌de_g🎷]

That's also undefined, but I can't tell what it's for. I doubt all of this stuff would be left undefined; are you missing some other base file or variable setup?

[Snowpaw]

I got it straight from the workshop, so I don't think so.

I checked and everything is there.
