Can you post whole client-side script? And whats' debugscript saying?

Full code would be really useful as LabiVila said. However, if you want to take money from specific player, you must pass a player through triggerServerEvent.

triggerServerEvent("itens", localPlayer) 

And to get player server side, use source.

takePlayerMoney(source, 500) -- You don't need tonumber here. 
local currentgivem4 = getElementData(source, "M4") or 0 
setElementData(source, "M4", currentgivem4+1)

When the player has 0 cash and purchase the item below ..

He gets -500 What do I do to not cash their money?

[LabiVila]

  
if getPlayerMoney (source) > 500 then 
    takePlayerMoney (source, 500) 
else 
    outputChatBox ("No enough money", source) 
end

it is >= not just > because the player may have 500$ so right code is :

if getPlayerMoney (source) >= 500 then 
    takePlayerMoney (source, 500) 
else 
    outputChatBox ("No enough money", source) 
end

if getPlayerMoney (source) >= 500 then 
    takePlayerMoney (source, 500) 
else 
    outputChatBox ("No enough money", source) 
end  

Doesn't matter, it still works (tested it more then 100000 times and still works by using > instead of >=)

Sorry for going off topic @michaleamir but once he understands how it works, then he can easily manipulate with such stuff
