Excel Lookup and Replace

I have an Excel workbook which contains 2 sheets. I want a macro to change the value in the main sheet based on the look-up table in the second sheet. The values in the first sheet are simple street addresses, the second sheet contains the same street address in one column and a corresponding number in the second column. I need to have that corresponding number automatically replace the street address each time it occurs in the main sheet. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition: 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
