one to many...ok here it is. I have two tables, Transaction ID and Card Transactions. Card Transactions has a field titled ID that uniquely identifies each record by a number for example, 0001, 0002, 0003, 0004, etc. As for the rest of the fields in the table, the fields jus describe the data. In that same table, I have a subdatasheet from 'Transaction ID' that lets me know which cards from my inventory were sold by way of the 'card id' field from my card inventory table.
anyways, so I am only able to enter a new transaction id in that specific field in that table. Even tho, the transaction ID table has that same field, it will not let me add a record with a new transaction number that hasn't been used yet in the card transaction table. it gives me the following error message...
"You cannot add or change a record because a required field is required"
