I have created a drop down list to point to a SharePoint library, however once I have selected a item and other fields populate because I have created rules, once I click that drop down and change the item it does not auto change the other fields. What am I doing wrong?

Well - it is most likely you don't have a filter to set the values to the right item in the repeating data source - can you post a screenshot of one of your rules or a copy of your form? Under the options tab... :)
