Need help with a small add on I'm making

[haZardous1617]

I'm making this add on/script for darkrp, that will jail someone on death and increase jail time if they have crime. (jail time increases hasn't been added yet)
So far this is what I have and I cant seem to get it too work...

local crimecount = 0

hook.Add("PlayerDeath","CheckKillCount",function(ply,dmg,attacker)
           if attacker:Frags()%1==0 then
		   print(crimecount)
                   crimecount = crimecount + 1
           end
end)



function GM:PlayerDeath( ply, inflictor, attacker )
	if crimecount > 1 then
	print(crimecount)
		RunConsoleCommand("darkrp arrest "..ply)

	end
end 

The error I'm getting is lua:12 attempt to index global 'GM' (a nil value), I've tried to remove this the error doesn't pop up but it wont work at all.
Thanks to anyone who is willing to help in advance! :)

You're not storing the variable to a player, and you're not using a hook for the second one. Also, %1 always returns 0.

hook.Add( "PlayerSpawn", "CrimeShit", function( ply )
	ply.crimecount = 0 -- Make sure crimecount always exists and is reset
end )

local crimetime = 30

hook.Add( "PlayerDeath", "CrimeShit",function( ply, _, attacker )
	if ( attacker:IsPlayer() ) then
		attacker.crimecount = attacker.crimecount + 1 -- Increase crime
	end
	
	if ( ply.crimecount ~= 0 ) then -- If the player committed a crime during their life
		ply:arrest( ply.crimecount * crimetime ) -- Send them to prison
	end
end )
