I just tried to update my message to say that maybe your data is normalized...but you replied too fast :)

The next question is why 16 fields? Is this just a guess of a maximum number there might be? What if business requirments change? As a child table, getting the data for the report becomes a simple join. For data entry screen purposes, you can still show it the same way as you currently are.

>The data is normalized, although I understand why one might think it is not. But you make a good point about the field length hitting the limit of 254 char. So I have to rethink the strategy of displaying the fields. Thank you for your input and suggestions.
