Testing Membership Plugin with Coming Soon plugin

I am about to launch a site, but in the meantime, I'm running a Coming Soon plugin. The membership needs are as soon as the website is launched, so I want to be able to test this Membership plugin. When I go into the Widgets, I see options for the Membership plugin, however which ever once I input, it doesn't work. I also make sure that I'm changing the "View Site As:...." and it's still not working.

What did I miss?
