Cannot embed form in Page - Wordpress

I go to the edit Page section. Select the right form from dropdown, but nothing happens after Submit.

The preview is working fine.

Thanks

I've done everything I can think of to get this to work! I can't get any of my forms to insert into my post pages (or anywhere for that matter!). I just purchased the GF Developers License yesterday. I am using Wordpress E-Commerce with Storefront Elegance Theme. I've cleared the cache(s), used several different browsers - even to the point of installing a new one! I've restarted my computer, I've checked for plugin/theme conflicts.

I purchased Gravity Forms with the hopes that it would be as easy to implement as it claims to be, yet I see many people are experiencing this same unresolved problem. I haven't given up hope, but I losing a lot of sleep over this (not to mention valuable time!). I don't want to bother with CSS, I am wet behind the ears when it comes to this stuff. This is another reason why I justified the expense of this plugin - it's supposed to be simple, right?

Can someone *please* help me to resolve this problem? Due to the nature of my business (http://www.customaed.com) I am hoping to use several custom forms which would post to individual product pages.

For the record, I am using the most up to date version of WP, WP E-commerce, and Gravity Forms. (as of June 16, 2011). I have tried inserting forms while on Safari, FireFox, and Google Chrome. I have also added the PayPal Add-on.

I can't tell you how many posts I've read trying to find a solution, only to view the same response over and over again. I just can't seem to get it to work for me.

Thanks in advance for this most desparately seeked solution!

Please help.

Thanks.
