Prices Not Going Into Cart

[RouX]

I have uploaded a partial test site to http:\\www.the-broch.co.uk and all looks ok.
But if you add something to a cart (Manufacturer >> Car Plan >> pick any product) the cost is coming through as 0.
As I have multiple "sizes" against products I have done this using a component, then an attribute, and then choices.
Within the component under permutations I have override selected and the relevant costs entered. I also have linked products at 0 cost with a weight assigned to calculate the shipping.
The dummy shipping values seem to e going through okay, but not the actual costs.
Any advice on what I am doing wrong?

You have not defined a price for each of the componets, once you do this and select the sum of componet prices in the product tab it will work - its all explained in the user guide.
