Knife kills player but doesn't award cash, Why?

This is part of a script that is responsible for damaging the opponents health as well as reward the player with 10 FCash, 1 Spree and 1 Counter. It kills the opponent but doesn't give me cash. Why?

local HitPlayers = {}

local LeftButtonDownTime = nil

local Attacking = false

function Blow(hit)
	if Attacking then
		BlowDamage(hit, Damage)
	end
end

function BlowDamage(hit, damage)
	local humanoid = hit.Parent:FindFirstChild('Humanoid')
	--local player = PlayersService:GetPlayerFromCharacter(hit.Parent)
	if humanoid ~= nil and MyHumanoid ~= nil and humanoid ~= MyHumanoid then
		-- final check, make sure weapon is in-hand
		local rightArm = MyCharacter:FindFirstChild('Right Arm')
		if (rightArm ~= nil) then
			-- Check if the weld exists between the hand and the weapon
			local joint = rightArm:FindFirstChild('RightGrip')
			if (joint ~= nil and (joint.Part0 == Handle or joint.Part1 == Handle)) then
				-- Make sure you only hit them once per swing
				if  not HitPlayers[hit.Parent] and humanoid.Health>0 and MyHumanoid.Health>0 then
					TagHumanoid(humanoid, MyPlayer)
					print("Sending " .. damage)
					humanoid.Health=humanoid.Health-damage
					Handle.Splat.Volume = 1
					HitPlayers[hit.Parent] = true
					if humanoid.Health < 0 and MyHumanoid.Health>0 then
						local leaderstats = MyPlayer.leaderstats
						local Counter = MyPlayer.Counter
						local Spree = leaderstats.Spree
						Counter.Value = Counter.Value +1
						Spree.Value = Spree.Value +1
						leaderstats.FCash.Value = leaderstats.FCash.Value +10
						HitPlayers[hit.Parent] = false
						wait(10)
					end
				end
			end
		end
	end
end

At line 30, try doing if humanoid.Health <= 0 and MyHumanoid.Health > 0 then
