Disable Button in Zone

[ZuKi|R]

Hi, I'm creating a function where I want to know that if the player is in an area, a button on a panel is deactivated (in this case I'm using setElementData and getElementData)
This is my code, please help me?
(I'm Using Google Translate Sorry)

 

------ Funciones --------


function asdfg ()
if getElementData(localPlayer,"EnZona") == "Si" then
guiSetEnabled(invisible,false)
else
guiSetEnabled(invisible,true)
end
end

You have to post the rest of the code. Where you're setting the element data and where you're using asdfg.
