Hi I have a custom list in which people who must capture on this list, should not be able to edit data on the list. The edit data should be restricted to only a few people

You can break permission inheritance to do this. Settings --> List Settings --> Permissions for this list. This will render a new permissions screen. Use Actions --> Edit Permissions You'll then get a dialog warning box advising that you're breaking permission inheritance from the parent site. Click yes and then add the users with the appropriate rights. You can always restore permission inheritance later.http://www.final-exodus.net
