MORE INFORMATION

The scope of a variable is determined by the way you declare the variable. In Visual Basic for Applications, you can use three kinds of variables: procedure, module, and public. To declare a global variable, use the Public, Dim, or Private keyword in the Declaration section of the module or procedure.
