Look at your data in the query. There is no record with a value in both fields (i.e. no item code exists in both tables based on that query) so there is nothing to add.
You would be doing yourself a favour if you didn't use special characters and spaces in your object names. You should not be creating multiple tables that look the same either. Access is not Excel, like where you might create multiple sheets that look the same. I think you need a primer in db normalization and design.
