Problems importing Excel data into FM Pro Adv v13
I've recently upgraded my FileMaker to FM Pro Adv v13. I've defined a table and am wanting to import an Excel spreadsheet. I've done this previously with FM Pro Adv v12 so I know what I'm doing. When I start the import process, I'm unable to select the table I want the data to go into. When I click on the pull-down list, I can see my list of tables, but they are all greyed out and are not selectable. The only option is to create a new table.
Attached is a screen capture of the window showing the table listings. The table I want to import to is called MacrTable. Is there something different with v13 that I need to do?
