Hi I have a select field titled "Owner". When a user adds a record to the database the owner select field is automatically set to the userid of the record creator ( I have all of the userid's of users in the select field). Now if the user wants to change the owner field to someone else I want a error message to come up..something like..."you cannot transfer ownership to another user. A user can only transfer ownership to their self."

And if the the person modifying the record is setting the owner field to their self then everything should go through fine. Any ideas how I could do this?

Any ideas will be appreciated
