Better usability on mobile

Better usability on mobile

So I've created a form.  When I go to the URL on iPhone in portrait orientation, I cannot see the entry fields to the right. I only see the field descriptions, and it isn't clear that the boxes are over there.  Pinching and stretching doesn't seem to do anything.  Changing the orientation to landscape, I can then see that there are boxes over to the right that need to be filled in.  This is confusing.

On a Galaxy, I can at least scroll to the right when in portrait orientation.  But how would I know to do so? The scroll bar doesn't appear at the bottom until the user starts sliding side-to-side.  When in portrait mode, how would the user know to do that?
