Preventing Google Analytics script on specific page

Hi guys

I'm using the Google Analytics+ plugin which I really like.

I'm also using Jigoshop and unfortunately, the script that is inserted by the GA+ plugin is conflicting with Jigoshop's built in GA E-commerce tracking that Jigoshop fires on the "Thank You" page.

So I need to stop the GA+ plugin from inserting the script on the "Thank-you" page.

I guess I need a wp_dequeue_script wrapped in a conditional if(is_page('thank-you'))

Can anyone help?
Thanks, Martin
