I am trying to follow the steps on this page below to install Zillow into my Zoho CRM but I can't seem to get it to work. Does anyone know how to get this to work properly? 

I think it may have something to do with the step on Importing the Zoho JS SDK, I am not sure how to correctly do this step. 

Any tips would be greatly appreciated, thank you.
