TSA Title:   "94: Invalid use of Null" error when clicking OK button on Event Recurrence Setup form
Builds Affected:   Build 1.1
Status:   Resolved in SR1A
Category:   Events
  
Problem/Issue Description
While attempting to make an event recurring through the Event Recurrence Setup form, after clicking the OK button the following error message is received:
"94 : Invalid use of null"

After clicking OK, a second error message is received:
"An error occurred during the creation of recurring Events"

After clicking OK, the Event Recurrence Setup form is closed and you are returned to the Event Detail Form. The event is still a single occurring event.
Cause
The event's "Setup Duration" or "Tear-down Duration" is blank (has no value).
Resolution
NOTE:  Resolved in EH2004 SR1A

(1) From the Event Detail Form, unlock the form using the yellow key unlock button at the top of the form.
(2) Make sure that a value is entered for both the "Setup Duration" and "Tear-down Duration" fields. If no setup and/or tear-down time is required, enter a 0 for the value. Do not leave these fields blank.
(3) Click the Save button to save your changes.
(4) Click the "Make Recurring" button to proceed with creating the recurring series.

This problem will be resolved in the EH2004 "Service Release 1".
