Please reply fast is important

Try this:

Add this css to the bottom template_css.css:

.column_right{
position: absolute;
right: 0;
top: 0;
}

It fixes the problem a bit, the right column goes to the correct position, but the template complete messes up. Bets Center becomes white... and loses it's form.
Also the code you gave me messes up the template more in other pages the right column goes through the security and trust. Please give me something else!!!

Ok, i discovered, problem is in some content on that page , you have opened some div and not close it, or you ave closed twice some div so rendered layout is incorrect.

Use validator.w3.org

Look at tag not closed exceptions.
