Did you read the error? GetBoneMatrix needs a number but you're not giving it anything. Check if what you try to call GetBoneMatrix with is a number before calling it.

Do you want the code because i am so bad

if CLIENT then
function SWEP:ViewModelDrawn(vm)
local vm = self.Owner:GetViewModel()
local matrix = vm:GetBoneMatrix(vm:LookupBone("v_weapon.c4"))

local pos = matrix:GetTranslation()

local ang = matrix:GetAngles()
local ang1 = matrix:GetAngles()

ang:RotateAroundAxis(ang:Up(), -90)
ang:RotateAroundAxis(ang:Right(), -90)

cam.Start3D2D(pos +ang:Up() *-2.7, ang, 0.1)
draw.RoundedBox(0, -13, 18, 15, 29, Color(0, 0, 0))
    cam.End3D2D()

if self:GetNWString("---") ~= "" then
        cam.Start3D2D(pos +ang:Up() *-2.7, ang, 0.1)
    draw.RoundedBox(0, -12, 18, 14, 29, Color(65, 65, 65))
        draw.RoundedBox(0, -13, 18, 2, 29, Color(0, 0, 255))
        cam.End3D2D()

    ang1:RotateAroundAxis(ang1:Right(), 180)
    ang1:RotateAroundAxis(ang1:Forward(), -90)

    cam.Start3D2D(pos +ang1:Up() *2.7, ang1, 0.018)
    draw.SimpleText("---", "DermaDefault", 138, -75, Color(255, 255, 0))
        cam.End3D2D()

    cam.Start3D2D(pos +ang1:Up() *2.7, ang1, 0.026)
if string.find(self:GetNWString("---"), "*") then
        draw.SimpleText(string.Replace(self:GetNWString("---"), "*", tostring(math.random(1, 9))), "DermaLarge", 73, -34, Color(255, 255, 0))
else
    draw.SimpleText(self:GetNWString("---"), "DermaLarge", 73, -34, Color(255, 255, 0, 255 -math.sin(CurTime() *8) *255))
            end
cam.End3D2D()
end
end
else

Entity:LookupBone isn't returning anything which means the bone doesn't exist on the viewmodel. You should define a variable for the bone and check if it exists. There's also no need to define your own vm variable since the viewmodel entity gets passed to the hook as the first argument.
