page is a mess

After I wanted to putt more tabs on the product page I edit the file show_tabular. The code seems to be fine, but the layout of the page all messed up. In the attachement you see the product page before and after. Can someone help me to get back to the right layout? I backed up the show_tabular file but putting it back on the server doesn't help

Hi

Please tell me the url to Your site and a path to this showtabular file, code for tabs is in our template overrides in file /html/com_virtuemart/productdetails/default.php
