Why would this script not work?

The leaderstats are working, it is this part of the script that is not:

local Humanoid = script.Parent.Zombie -- Or Zombie Or Whatever 
function PwntX_X() 
    print("1")
local tag = Humanoid:findFirstChild("creator")
print("2") 
if tag ~= nil then 
        print("3")
        if tag.Value ~= nil then 
            print("4")

local Leaderstats = tag.Value:findFirstChild("leaderstats") 
print("5")
            if Leaderstats ~= nil then 
                print("6")
Leaderstats.Cash.Value = Leaderstats.Cash.Value + 5
print("7")
wait(0.1)
script:remove()
            end 
        end 
    end 
end 
Humanoid.Died:connect(PwntX_X) 

It breaks between print("2") and print("3").
