Widgets hiding my shopping cart

Hello –

I am having problems with my shopping cart sliding underneath the widget area instead of over it. The shopping cart is the Artful.ly WordPress plugin which is up to date, but unalterable from my side as the widget simply references things on their end which I cannot change. I’ve been told repeatedly that a new shopping cart is in the works and will be available “very soon” but after three months of repeated assurances I am beginning to think its a placating response.

Is there is a line of CSS I can put in the theme’s custom CSS box which will force the widgets to stay under the shopping cart? I am using evolve theme v. 3.4.2. (It is not updated because I like the slider style in this version better than the new version, and the widget problem occurred on both so updating would just make me unhappy all around.)

Here is a link to reference. Click the “Make a donation” button to view the shopping cart. (Enter an amount to see the checkout buttons in the cart – you have to go through several steps to actually checkout so there’s no worry of that happening accidentally…especially when the Complete Purchase button is hidden behind a widget. ha.)

Thanks for any help you can give on this! I’m the founder of this org and pretty much do everything so I can usually find work arounds on my own but this has me stumped!
