Whats the error with this kill npc money script? y output isnt help at all with this.

function MoenyGive() 
    local tag = Humanoid:findFirstChild("creator") 
    if tag ~= nil then 
        if tag.Value ~= nil then 
            local Leaderstats = tag.Value:findFirstChild("leaderstats") 
            if Leaderstats ~= nil then 
                Leaderstats.Coins.Value = Leaderstats.Coins.Value + 5
                    wait(0.1)
print("Money gave")
else
warn()
                script:remove()
            end 
        end 
    end 
end 
Humanoid.Died:connect(MoenyGive)

I am not 100% but I believe "Leaderstats" should be with a lowercase, also its better if you use a higher case on connect, such as "Connecet"! I have also re-written your code and added a function to the :Connect.

This most likely won't work but give my attempt a shot.

local Humanoid = script.Parent.Humanoid 

Humanoid.Died:Connect(function(MoenyGive)

function MoenyGive() 
    local tag = Humanoid:findFirstChild("creator") 
    if tag ~= nil then 
        if tag.Value ~= nil then 
            local Leaderstats = tag.Value:findFirstChild("leaderstats") 
            if leaderstats ~= nil then 
                leaderstats.Coins.Value = leaderstats.Coins.Value + 5
                    wait(0.1)
print("Money gave")
else
warn()

                script:remove()
            end 
        end 
    end 
end 

If this helps shoot me a reply.
