Hi ,

I am trying to compare start date/time and end Date/Time using Date/Time Prompt and prevent users from selecting start dates/Time AFTER the end date/Time, or vice versa Using Cognos 11.0.6 using custom control.Can you please help me with the javascript using custom control.

I looked into the below link but unable to add the time and i am poor at javascript
