Responsive forms & Javascript

Hi all,

I'm creating a responsive form in Innovator Release 30 and want to use a client method (Javascript) to fill in some fields.  With classic forms, I could use the getFieldByName method to reference the element on the form, but this doesn't seem to work with responsive forms.  I'm getting this error:

aras_object: "undefined" : "undefined"

Does anyone know how to get and set field values in Javascript for responsive forms?

Thanks,

Rob
