SMS To Users (hep! hack not working!)

Well I just happened to purchase a PAID account of Twilio - ASSUMING it will send notifications to users when they submit the form - my mistake.. as I did not read enough :( ..

Im not a coder bur I tried the modification of twilio.php as given by deweydb:

public static function export_feed($entry, $form, $feed){
       $body = GFCommon::replace_variables($feed["meta"]["message"], $form, $entry);
	   $twilioTo = GFCommon::replace_variables($feed["meta"]["to"], $form, $entry);

       self::send_sms($feed["meta"]["from"], $twilioTo, $body, $feed["meta"]["shorten_url"]);
    }

The only line I added to php file at the given code is:

$twilioTo = GFCommon::replace_variables($feed["meta"]["to"], $form, $entry);

then I went and updated the twilio settings "To Number" with a merge code from Gravity forms using "insert merge code":
{Phone:5}

Well its not working - I tried filling the forms but I do not get a notification to any valid mobile number I enter..

Can someone please help!?
