Correct Table Structure - Optional Values

Hello,

I have 3 optional text boxes. I don't know if the best way to set up
the table would be a field for each box, since this would leave gaps in
the table if the user only filled in one box. Is there a good method
to use?? This is kind of like storing check box values, in that there
could be multiple answers.traceyburger@.sw.rr.com wrote:

You don't give us much to go on but based off what you said, it sounds
as if the data that goes in these text boxes should be in their own table.

What do you mean with gaps? With this miniscule information, it sounds
to me that the columns mapping to these text boxes should be nullable.
Thus if a user only enters value in one box, you store NULL in the other
columns.
