Alpha Cipher

The letters A to Z have each been allocated a different number between 1 and 26. The number next to each word in this list is the sum total of the letter values in that word. So, for example, in HIP, H might equal 22,

I 5 and P 17, or H might be 9, I 24 and P 11, or any other combination adding up to 44. We’ve placed some starter letters in the grid at the bottom — can you work out the values of the rest?
