I guess you will have to use recordsets to do this. You can probably do it in the insertrow() method of the repeater (I assume you're talking about a repeater here) or the postinsert() method of the column object itself. Here's a guess at the former. I have not tested this. It might need to be in postinsert(). You might also look into saving the value in a user defined variable somewhere and grabbing it during insertrow. Let me know if this helps or not.

repeater.insertrow(rownum)

inherited.insertrow ( rownum )
r = self.getrecordset
IF rownum > 1 THEN
  r.setcurrow ( rownum - 1 )
  theval = r.getcolval ( "colname" )
  r.setcurrow ( rownum )
  r.setcolval ( "colname", theval )
END IF
