The bottom of the page at:

has a comment about the type mismatch error.
It indicates that your text box has a non-date value in it.

If you have other code you want to use in the same event, you can use:
Call CalendarFor(Me.[VisitDate], "Select the visit date")
in your existing event procedure.

I am trying to incorporate a pop up calender from Allen Browne. Downloaded
the file (for Access 2000 and later) from the address below and unzipped
it.
http://allenbrowne.com/ser-51.html
I followed the instructions and also pasted the calendar button, changed
the name of the field to [VisitDate] in the onclick event as required. The
[VisitDate] is a date field and formatted for short date.

But when I click the button a type mismatch error occurs. The [VisitDate]
has some after update events already written. Is that the problem? Should
I
paste the button first and then re-write the after update events?

Any help will be greatly appreciated.
Thanking you in advance
Leo
