value returning from a calandar

[Smiles]

Good day

Last year someone advised me on a popup calendar called frmCalandar I am
using access 2000

this calender works fine and I use it to find a record
now I want to change the form to give a new record

I have a text box that is bound to the value of the calendar
"txtenddate" from which I use a select query giving the corresponding
record to it.

I would like to delete an input form which is a copy of this form and
use this query to find or give a new record.

criteria is "[Forms]![control form]![txtEndDate]"
"txtEndDate" is a hidden text box on the form

How do I set a new record if date is not found?

thanks
