|... but did you change the size of the output box? or txt box for data entry?|
I would check again. This is an error for the control not the table.
Thinking on this: Let me add to check the column widths of the combo box in case it is a horizontal issue. If it is a vertical issue, you may need to use an SQL statement to fill the box, but if memory serves the combo box has a limit on how big vertically - check the height and width of the combo box in the properties too.... Let me know ... I'll keep thinking on this one.
I'm still learning everyday.
