  Hi:
  

  
  

  I really need help, I can not figure how to create a global variable that can be changed and used in
  

  several classes.
  

  
  

  I got many suggestions, but i can not make any of them work, always get errors...
  

  
  

  the last solution i tried was doing a "afile.h" where i put the variable using extern... but then i got "linking" errors...
  

  
  

  How can i solve this problem? I just need a boolean variable that can be "seen" anywhere...
  

  
  

  Please help me, if possible write down the code, because each word I write today as at least one error...
  

  
  

  Thank you in advance
