"Bound" means the form "knows" what set of data it's referring to. You can
make a form without giving it any data source, but it won't be "bound" to
any data source!
If you open your form in design mode and check its properties, the
RecordSource property tells you what the form is bound to.
I don't understand why you were trying to use the DateAdd() function in your
table ... does this mean you wanted to take some other field's value and
store a calculated value based on it? (This isn't a good idea, usually).
You can do whatever you want to the controls on a form, but that doesn't
change the table's definition.
