/**
 * This is a snippet for the Gravity Live Summary Pro addon (http://geekontheroad.com/live-summary-for-gravity-forms/)
 *
 * It will modify the columns displayed in the live summary mergetag by modifying the underlying templates
 * In this case it will remove the QTY and UNIT columns from the live summary mergetag 
 *
 * By Default this code will apply to all forms but it can be limited by adding form-ids to the allowed_forms array at the top of the function.
 *
 * Copy the below code to your functions.php or code snippet plugin
