Getting A Textbox To Populate Based On Another Textbox

Dear All:

I have created a form using access 2000. So far, this form already has data and dates in a combox in this format: mm/dd/yyyy.

In the AfterUpdate of the date combobox, I did this:

If graduation_date = #2/1/2004# then
Text_Graduation_date = "dated this first day of february two thousand four."
End If
End Sub

In addition, I have defined many other dates as well using the code above. It works well when I choose the date form the combobox, the other textbox populates, but there are so many more dates in the combo!

Is there a way to auto-populate the textbox with the appropriate text as I scroll through the form?

Thanks,

Dion
