Different pricing depending on option selected

Hi i’ve got a product that has lots of different prices depending on size and thickness.

What i would like to do is set the page up so the customer first selects thickness then it opens the sizing input with the pricing for that thickness.

Is that possible? You can see my page here and what i’m trying to acheive https://halman.brandabble.co.uk/product/somerset-finish/
