Changes in Virtuemart

I have a site in spanish language with Joomla 2.5 + Virtuemart 2.0, it have some special process to obtain prices from webservice, this option auto update each 30 seconds and autoupdate the virtuemart products, this option is already done and we mark this products like "dynamics". The tasks are: 1. For some reason VM dont sent the info for the dynamics products to Paypal when I choose payment method and proceed with the order. 2. When I delete a product in the cart the page refresh with no styles. You dont need a login to test it. 3. When I accept Terms & Conditions and select Buy Now the cart lost the css style again. 4. In the table details for the products added to the cart, the titles are in white, need to be changed to other color (background in white too) 5. In view cart -> confirm order the cart lose the styles too after the new shopper fill his info. I need this done ASAP, in PM I can send you the URL for the site. I'll going to delete any quote If the provider dont ask for the url for test befor to confirm terms.
