in thread obtaining yyyy-mm-dd via a calendar object

How do I get this calendar widget to work within a CGI form?

At a first glance, you need to feed the response into a form variable, so that when you submit the form, the calendar information will be passed into the CGI paramters sent to the form's action target. You'd likely feed the response to the variable via Javascript, but the rest is bog-standard HTML form work.

Does that make sense? Sorry if it's short, I just got back from vacation...

    Welcome back from what is hoped was a relaxing break. OK, we're almost there! Without changing the calendar widget code from Reply 9 in the previous thread, following is the code used to implement your suggestion.
    When the below code executes, it results in an internal server error. Interpreting this to mean that code is not finding the CalendarWidget.pm perl module. Can you discern what my problem could be?
