Your question is vague. Within your code, what is declared global? Is the variable declared global in ALL functions you wish to use it in, using the same exact name?

Also, the global variable persists only as long as it is a live-variable in at least one function. If you declare a variable global in a function, and that function ends, the variable will be de-allocated. Attempting to declare the same variable global in another function will result in creating an empty "double" value.
