If you run into issues only after adding your included files, this shows that there is some sort of conflict with the included files. Do you have a link to the page or is it still only on a local server?
As for making a map that users can search for addresses, this is possible. You will have to create a form that contains one form field for each value needed to map a location (street, state, zip, etc). Then you would bind the form fields in the Pro Maps wizard to the correct values.
