    "... in the define.h file it not working"

    In what way, exactly, is it "not working"?!

    How do you expect anybody to help to fix your problem if you don't actually say what the problem is?!

    If you phoned a mechanic, and just told him that your car was "not working", do you think he would be able to do anything based on that??

    Anyhow, as we're talking header files, what normally happens if you put a variable definition in a header file and then include that in multiple places...?
