Judith, try not to use the terms "rows" and "columns" when working with Access. Those are spreadsheet terms (like in Excel) and can confuse you in Access.

In a database, we have FIELDS (columns) and RECORDS (rows). So did you delete a couple of fields, or records?

I'm assuming you mean FIELDS, and the "rows" you're talking about are actually the TABLE DESIGN equivalent for fields (since they look like rows on the screen).

Now, if you make a table, then build a form off of that table, then go back and delete FIELDS from the table, you might get the "Enter Parameter Value" box up when you open the form because Access it trying to find fields that no longer exist.

You'll have to open the form up in Design View and remove those fields off the form too. Plus, if you have a QUERY between the form and the table, you'll need to clean that up too.

Hope this helps.
