Great, thank you. Can you try injecting without using the Admin option (Browser / Sandbox) then add a rule to QdabraRules finishedLoading attribute that when finishedLoading = true, set useWebServices (in the QdabraRules Form group) to true?
Then try again in the browser - this will make the form use web services like it does in preview. You aren't using Office365, right? This option won't work with Office365....
