Add/Edit Shipment Address in Cart page can't be clicked

[JuanSender14]

I have list of products, I fill in it's name, category, weight & dimension and other infos. Then made one shipment method.  But when I go to the frontend and tries to purchase a product, the "Add/Edit Shipment Address" is not clickable even I already added the Billing Address Information. What is wrong with this? By the way my shipment method is based on "weight,zip and country" and I set the product to have 0 weight , no zip and available to all countries.

I am using Virtuemart 2.0.26 and Joomla 2.5.16

@jenkinhill: Yes sir I'm using one page checkout right now

Try without OPC, which was rewritten for the 2.0.26 series

Have you got a URL?
By how you are describing it, this may be a CSS Z-index issue.
