My form link doesn't work.

Sometimes when I send it to a client to save to their desktop, the form doesn't work. It reads whoops error. And then if I send it again It works. It's inconsistent. And it has happened with numerous people. Help, 

It seems the form URL which you are using it not correct. The domain is not correct and there seems to be a "." at the end of the form ID. 

The correct URL of your form should be:   https://www.jotform.com/73474386184163
