I am the 18th person to download the new plug-in, "Gravity Forms Quantity Limiter." It shows up in the list under "Forms" where it's supposed to show up, and when I select it I get the choice to choose a form to apply the plug-in to, but nothing else shows up on the page. There's no button to click or any options to choose, and when I leave the page it isn't saving it.
I have confirmed that I have a form with a single product and quantity defined. Nothing is happening. I have tried it in Firefox, Explorer, and Chrome.
