See this demo file. It uses a name field to look up the ID number--kinda reverses the standard approach. Scripting is used to manage the process and handle situations where there might be identical names.

Thank you for your help. Your example helped me create the auto complete function on my project.
I have another question about this auto complete name / drop down list name field and instant web publishing.
Is there a way to manually type in information like a name in a drop down list field in IWP? In the browser, the only input is the drop down menu, you can't type in the field. Thanks, Steve
