[otrs] Please select a queue

I would like a "- Please Select -" at the top of the queue list for a new customer ticket. I tried playing with "CustomerPanelOwnSelection" and get the proper list, but if they select "- Please Select -" (which is not a real queue) they get a "Error: Need TicketID! " error. Is there an easy way to give just a "you need to select a real queue" error? -- -- Steven http://www.glimasoutheast.org
