This is not a live site. There are a couple of problems. One is that in order for the Java script to pick up the price the H2 heading has to be changed to a span (apparently - I am no expert) which throws out all the following formatting. There is also a tax inc/exc mod but I don't think this is causing any problem.

The second problem, which I haven't looked at yet, is that 'checkout' button on the shopping cart page is covered by the converted price making it impossible to proceed any further.

Just a pointer in the right direction would help - I not looking for a free lunch!

Cheers
