How to add value (£) to worded cells?

My objective is to find the total value of a customisable product.

1. The top right table with the attributes, each need to have a monetary value, ie tall = £10, wide =£20 etc

2. In the third table, with the combinations, it needs to be printed out in another table so the string looks like this:

Tall-Black-No-No-No-No-No

With each attribute separated with a hypon.

3. Finally, I'll need to find the total value of that string.
I've tried racking my brain to figure out how to do this, but I am just not making any progress. I hope someone will be able to help!

many thanks in advance!
