Need shorter url for survey

I am trying to use a short url, Tinyurl.com with my survey.

When I try it, it just opens up a blank form

You need to create first the custom URL name of your form before you shortened it using the TinyURL service you were using. Use the custom URL name of the form in TinyURL

Let us know if this did not work.
