question, team by rank

[side]

Good afternoon team, excuse me, my question is
How can I create Teams for the next level system? 
example for rank 0 to rank 10, beginner, etc, i thank you in advance.

addEventHandler("onElementDataChange",root,
function() 
	if getElementType(source) == "player" then
    local zombiekills = getAccountData(getPlayerAccount(source) ,"Zombie kills") or 0
if (zombiekills >= 0) and (zombiekills <= 10) then 
setElementData(source,"Rango","Rank/1.png") 
elseif (zombiekills >= 11) and (zombiekills <= 99) then 
setElementData(source,"Rango","Rank/2.png")
