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?
