I need help with this function, check if there's bug in it please. 
 
function hospital( player, source, commandName, posX, posY, posZ ) 
    if (source == hospitalButton) then  
        exports.texts:output("You are now on LV Hospital! ", source, 0, 255, 0) 
        setElementPosition ( source, 1614, 1817, 10 )  
        end 
end 
addEventHandler ( "onClientGUIClick", guiRoot, hospital, false )
