Unable to configure sonar on mission planner

Hi i’ve connected 2 MB7366 ultrasonic sensors to pixhawk through ADC3.3v. However i cannot seem to configure my ultrasonic sensor on mission planner

Why not? What have you tried already?

yea i tried following the steps from http://ardupilot.org/copter/docs/common-rangefinder-maxbotix-analog.html but the sonarrange in the status tab stays stagnant

I also did it following this guide a few days ago and it worked.
Did you reboot the AP after config? I think I’ve read this somewhere.

if i connect both my ultrasonic sensors to ADC 3.3v when i set it up i put the pins as 13 and 14 right? im getting a reading of either around 1.7 when there is nothing in front and around 0.5 when there’s an object in front of the ultrasonic sensor, is that right?
