I am trying to use the Microsoft Date and Time Picker control and I am getting the following error "an error occured in a call to the windows date and time picker control" in access 2000

I am trying to use the Microsoft Date and Time Picker control and I am
getting the following error "an error occured in a call to the windows
date and time picker control" in access 2000. I have not been able to
find any information on how to configure the controls properties, and
I also get another error "Can't set value to null when checkbox
property = false". If I set that property to True than I get a
checkbox in the controls inputbox which I do not want. The last error
seems to be cause by the fact that I am adding this control into an
existing database and some of the records that will use this field
will not have data in it. I like the look and feel of this popup
calander control, the only other control I have found in access does
not seem to work the same way. How can I get this control to work with
out error ? Where can I find a manual on what all the property values
are and how the work.

Thanks for any and all the help I can get,
