Hi Eric,
Moved your post to the Report Design forum.
What you are doing is correct but not enough info on how the tables relate to each other. When dragging field to field in the Linking Wizard the default is a Left Outer Join so you will get multiple rows with the same numbers.
If the linking is correct try this:
Check on the Suppress if Duplicate and see if that's what you need. But I suspect you need Links or a Command Object to get the data you really want.
Need more info and details about the tables you are trying to link.
