Rails spinoffs - Jul 2007 - Now I am dragging and dropping - how do I add things up?

Not the best at javascript/ajax/making coffee as google has been my
teacher, but I am constructing a ''wedding calculator''

http://www.blakelands.co.uk/Cart

 to calculate a price based on the items dragged into the ''shopping
cart''.

How would I assign numeric values to these products (without the use
of mysql) and have it dynamically adding up in the last box?

You are talking to someone who is incredibly dim so please break it
down if you can!

Thanks muchly

An easy way to do this is to hard-code your wedding items as a JSON
object.

You could then grab the details from the JSON object based on the ID
of the cart item.
