Auto populate infopath form fields

Hi Everyone,

I have a InfoPath form with a drop down list control. The data in this list is pulled from a standard sharepoint list that contains several other important pieces of information.

How do I get other fields in the info path form to auto populate with other values from the same sharepoint list. For example, if the user selects a project number in the form, the form fields forclient name and project lead automatically fill in.

Any assistance would be much appreciated.

Thanks!
