I added an anti-TK precaution to a sword script, however since then whenever it hit a part that was welded to a player such as armor, it stopped working.

I always get this error message: attempt to index nil with 'FindFirstChild' from the line containing "if humanoid" If I need to add an "else" statement, what should I do? How else can I improve this script?

if hit.Parent ~= nil then
		local humanoid = hit.Parent:FindFirstChild("Humanoid") 
		local eTeam = hit.Parent:FindFirstChild("Team") 
		local vCharacter = sp.Parent
		
		if vCharacter ~= nil then
			local vPlayer = game.Players:playerFromCharacter(vCharacter)
			if vPlayer ~= nil then
				local hum = vCharacter:FindFirstChild("Humanoid")
				local friendly = vCharacter:FindFirstChild("Team").Value
				if humanoid then
					print ("Enemy Found")
					if eTeam then
						print ("Team Found")
						if humanoid ~= hum and eTeam.Value ~= friendly then
							print ("Enemy Found")
							local right_arm = vCharacter:FindFirstChild("Right Arm")
							if right_arm ~= nil then
								local joint = right_arm:FindFirstChild("RightGrip")
								if joint ~= nil and (joint.Part0 == sword or joint.Part1 == sword) then
									sp.Handle['CutSound'..math.random(1, 2)]:Play()
									tagHumanoid(humanoid,vPlayer)
									humanoid:TakeDamage(damage)
									wait(.3)
								end
							end
						end
					end
				end
			end
		end
