Hi Peter,
Please follow this solution:
1 Open your list mapping.
2 Delete two links to the "City.Text": http://prntscr.com/45319x/direct
3 Click on "add js" on "mobileListitem_29" and populate it with following code:
pre
element.find("h3").text(value.city + ", " + value.state);
/pre
That's all.
Regarsd.
