Text wrapping around the product image

I'm new to the cart, using Zen Cart version 1.39, and Andover Modern template, I'm trying to prevent the text in my product description to wrap the image toward the left. There is a post to modify the stylesheet.css:
#productDescription {
width: 60%;
float: right;
}

but in my template I can't find that line.
Here is link to my product

http://fishclubonline.com/etackleshop/index.php?main_page=product_info&cPath=7_10&products_id=10

Can somebody help me with this? Thanks

First you need to delete your stylesheet_bak.css file
as any file ending in .css is loaded

Then in your stylesheet.css file find and edit this rule adding the following and adjust to suit

#productDescription {
        color:#000000;
        width: 500px;
        margin: 0em 0em 0em 5.5em;
        }

but in my template I can't find that line.
It is there as #productDescription

It works!
Thanks so much, you'be been a great help. Now I can move forward.
