Conditional headaches

So, I have a form that needs to collect between 1 and 20 name/email combinations.  I'm trying to keep it clean with a drop down to select the number (from 1 to 20) and then display the appropriate number of fields.  This is not working as expected.  What I tried first was if the dropdown was blank, hide all of the name and email fields as well as the submit button.  I then added a 2nd rule saying if it is equal to 1 to hide 2-20 and not the submit button.

What happens is all fields are displayed.

What am I missing?

Thanks, Rob

Figured it out using the Form Collapse and an example.
