New Post: Dropdown field sending null on form submission

Excellent suggestion. I've tried it both ways (ControlMode="New" and ControlMode="Display") but neither will submit the value that is set in the dropdown to the list. I'm trying it out using a People Picker instead of a lookup dropdown field and using SPGetCurrentUser() on the People Picker as described in Tanveer Khan's blog post (http://tanveerkhan-sharepoint.blogspot.ca/2011/09/populate-current-logged-in-user-name-in.html?showComment=1361374050955). I'll let you know if it works.

Thanks for the reply Matthew.
