How to remove unwanted lines above Add to Cart button?

Hi. Please see the attached image. I want to remove unwanted lines between attributes and Add to Cart button. If possible, I want to remove Add To Cart box also.

Here's the link to the site in case the image doesn't work: http://www.cedardelight.com/index.php?main_page=product_info&cPath=1&products_id=10

How can I do that? Thank you for your help.

Yc,
Locate this:
includes/templates/red_passion/css/stylesheet.css

Find this:
#productDescription, .shippingEstimatorWrapper {
margin-top:-5em;
padding:0.5em;
}

2. Notice the highlighted red font above in the declaration

3. This is what you will add

Hello, haredo. Thanks for your reply, but that entry decreased space between Add-to-Cart button and listed description part(Handcrafted from beautiful...), not the space between Attributes and Add-to-Cart button. Any ohter suggestion? Thanks.

I've kind of figured it out myself. I modified "tpl_product_info_display.php" in includes/templates/tempate_defaults/templates. I wrapped the sections from <!--bof Product Price block --> to <!--eof Add to Cart Box--> with a simple table structure (<TABLE><TR><TD>...</TD></TR></TABLE>), and now I've achieved the result that I wanted. Thank you for your help anyways haredo.
