I am sure this is something simple but as a newbe I can not work it out.
I want to change the lay out of the product page product.tpl
I want the picture to display on the left, as it is, details, options, Add to cart on the right of the picture, fine worked this out, but I can not get the product description to display the full width of the box underneath the picture and product details.

Could some one help please, I am sure it is simple and I am overlooking something!!!!

Many thanks Ellenor
