Intangible Assets with only share value percentage and Goodwill Value

I am wondering if someone can urgently assist I am working on a scenario for example:

In March 201x, Dimension Ltd acquired 70% of the share capital of DataComms Limited, a company that specializes in designing and developing economical printing machines. Goodwill of £3,700,000 arose as a result of this business combination.”

It then has Research costs over a 5 month period & Development & Productions costs at the end of the 5 months with Orders 2 months later. and finite life of 4 years before a new machine needs to be developed.
Customer List of a certain value with a useful economic life of a few years and staff training costs with potential profit costs.

My question is why can I not work out the carrying value as my head says I need either a consideration amount or carrying amount. This is part of a write up so I will not lose a lot of marks for incorrect answers but I am just struggling with a basic calculation it seems. I have done all my other questions but cannot work this one out.
Thank you
