Hi Tracy.

When the user types a new value into the textbox portion of the combo that doesn't exist compar the combo's Value to its DisplayValue. If it is not the same add the code to add the value to the table and requery the combo when your done.

This is will only work when the BoundColumn is column 1. The best way to make this comparison is to use code like this:

IF NOT EMPTY( This.DisplayValue ) AND This.ListIndex = 0
  *** The user has typed something that is not in the list
  APPEND BLANK IN Table_B
  REPLACE MyDescriptiveField WITH This.DisplayValue
  This.Requery()
ENDIF
