How do I make it in Office 2016 VBA probably, but I am going to use Access. I need to know how to create a option box with all the different envelope sizes and tests and inserting the header information of a letter and the body of the letter for multiple addresses that will be gone through with VBA or another way that I am told to do it. Please write me back at kevinconwell1@gmail.com. I am trying to get this done as soon as possible for a non for profit for the disable organization.

Thanks

Kevin
