Custom table item Selector syntax

I have a custom table (EventType) containing a list of event types (meeting, workshop, etc..). This type are in a text field named @TypeName@.I would like to display these types in a dropdownlist in the field of a different page type. The text field in this new page type will be named @Type@ and will store the selected event type coming from my custom table. I start playing with the Custom table item Selector but cannot find the correct syntax to make it work.What should I put in the @Format of the display name:@ and in the @Name of the value column@? I tried several options but none of them succeeded.Thank you for your helpS.
