Are both statements in the same scope?

If the SDV() call is directly in the PHP file, and the conditional is in 
a function, you need to have a  declaration in the function before you 
check the value:

   global $TotalCounterEnableGeoIP;

If they are in different functions, you need to have the global 
declaration in both functions.
