(SOLVED) How do I use function breakBreakGroup?

I'm just wanting to break individual groups to inspect damage without destroying the parts i'm removing. I'm no programmer, so it's no surprise i couldn't make it work. How do I use it?

Full function as it is written in beamstate.lua

local function breakBreakGroup(g)
if g == nil then
return
end

-- hide props if they use
props.hidePropsInBreakGroup(g)

-- break all beams in that group
local bg = breakGroupCache[g]
if bg then
breakGroupCache[g] = nil
for _, bcid in ipairs(bg) do
obj:breakBeam(bcid)
luaBreakBeam(bcid)
end
end

-- break all couplers
bg = couplerBreakGroupCache[g]
if bg then
couplerBreakGroupCache[g] = nil
for _, ccid in ipairs(bg) do
obj:detachCoupler(ccid)
end
end

--break triangle breakgroups matching the beam breakgroup
bg = triangleBreakGroupCache[g]
if bg then
for _, ctid in ipairs(bg) do
obj:breakCollisionTriangle(ctid)
collTriState[ctid] = nil
end
triangleBreakGroupCache[g] = nil
end
end


EDIT: figured out I was supposed to put beamstate before calling the function
