	87	Replacement Code At the bottom of page, last 2 sentences: should be: The following code sample illustrates how both the declaration and it�s location affect a variable�s scope and lifetime. Option Explicit 'Used to require variable declaration Public txtCustomerName as String 'Scope is entire application Private txtVendor as String 'Scope is any procedure in this module Dim txtSupplier as String 'Scope is the current module Private Sub GetCustomerName() Dim txtCustomer as String 'Scope is limited to this sub End Sub You might be wondering why the two statements that begin with Dim have different scopes. Use of the Dim keyword in the General Declarations section sets the scope of the variable to the module, so it can be used by any procedure in that module.. In the previous listing, txtVendor and txtSupplier are both module-level variables. They can be used anywhere within the module and anytime the module is loaded. txtCustomerName is a global variable. It can be used anywhere within any procedure in the application.	01/03/07
