I am trying to set up a table so that the same person can be added multiple times but only when another field is different. THe second field is a form header ID and the table is essentially the footer to the table. In other words, I want to NOT be able to add the same person twice for the same event (the header). This has something to do with the index button and I have seen it in sample MS applications but I cannot figure out the procedure to do it myself. Any suggestions/guidance are MOST appreciated.
