Price doubles when in shopping cart

[TraceyHand]

Where do I choose sum of components ??

again, in the Pricing Model option on the General Tab of the PRODUCT itself.
I agree with Darren. I'd set it up like that too but ONLY if the associated products, that you are linking to, have prices set (I assume they do) and you need to change the OVERRIDE to ASSOCIATED PRODUCT PRICE

You'd get the same result by changing the pricing model to product price though. Or SHOULD do! (This IS Actinic, remember )

Is there a quick way to change this option rather than going through all the products like a default or something ?
