WP e-commerce plugin, add to cart button problem and permalink adjustment

Hi Everyone,

I’ve created the sub-domain for my shop and I use WP e-commerce plugin.

I’ve add the details on single product page and found that the add to cart button was laid not properly.

Please find http://shop.buddhabucha.net/products-page/สร้อยคล้องพระ-คริสตัล-swarovski/สร้อยคอคริสตัล-swarovski-แท้สำหร/
and you will see the add to cart button at the end of the page was laid out of the box……How can I adjust this?

One more question, how can I change the permalink, I would like to set it manually one by one on each post.

I use:
wordpress version: 3.4.2
theme: AdStyle, author: Gordon French, (provided on wordpress dashboard).

Can you please advise how can I do this.

Thanks a lot,
Anchalee
