I'm trying to build an address book that I will print for my wife to use. I want to use Word's mail merge feature with an Excel spreadsheet as the data source. When I click "Select Recipients," I see my spreadsheet where I saved it: Documents --> MyDataSources. I see a preview of the list in the Preview pane. I double-click on the file to select it. I then get the "Select Table" dialog box, and the Table pane is empty. I can't do anything except Cancel. The "Workbook" selector shows only a couple of older Christmas card lists. What's going on?
