DC2NET Links

I have a shopping cart. The cart contents is database driven. When the user wants to click continue to purchase the items in the cart, I need to pass the cartID to the next page (order.aspx). However, I also need to recalculate the cart contents to ensure no quantities have been altered.

So I really need an onclick function to call the recalcCart function and then use PostBackURL (or equivalent). I can’t seem to find a way to do it.

I don’t want to use querystring or server.transfer (want to a move to the next page)

Any help would be greatly appreciated.
