I have a calendar that I created in the last version of the Events module.  I recently upgraded the module to the current version.  I just tried to send an email to some registered users and I get the following error.

Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

Any help on debugging this would be appreciated.

Here are the specifics.

1. Login to DNN as an admin.
2. Go to an instance of the events module
3. Click on a specific event within the calendar to display the specifics for that event.  Make sure that this event has at least one person registered.
4. Click on the Edit hyperlink for that event.
5. Expand the Enrollment Settings.
6. Select at least one person registered for the event  using the check boxes to the left of the registered users grid.
7. Click the "Email selected Enrolled Users" hyperlink.
8. Click OK when prompted about whether you want to email the enrolled users.
9. The following error then appears above the calendar.

Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

I have also attached a picture of the screen with the error.

Alan,

Any update on this issue?

Thanks,

Scott
