Question : Previous Month-end Date based on Date in Text Box

On a Access 2007 form a text box is formatted as Short Date and the Date
Picker can be used to select the a date for which a process will be run.

Part of the process uses the date selected as the criteria in a query to return data as of that date. From this same entered date I need to derive the previous month-end date for another query that will return data for comparison with that of the first query.

Assuming that the text box holding the selected date value is Text1 I have tried the following:

=DateSerial(Right([Text1],2),Left([Text1],2),0)

This works for the months of October through December, but the Date formats in Access don't create a true mm/dd/YYYY display so it fails for the rest of the year.

Sure.. Here it is with the changes I suggested.
