This is just a shot in the dark but you could add an Integer or Text
field to your audit table to indicate which field changed. Run a
query or VBA code to stick the number/name in the new field whenever
no value exists, then use that number/name to determine which field to
highlight. I've never tried to highlight a particular field on a
subform in datasheet view so maybe others can help you there. If more
than one field can change from record to record then create a new
table with the record identifier and a new line for each field that
changed. Then use the OnCurrent event of your subform to look up all
the fields that changed.
