vba code for math in a word table

Afternoon all,

I am seeking the aid of someone far more familiar with vba for word than I am as I am a relative newbie on the word side. I have a document (attached) that has a table that i need to perform some mathematical computations on. I can't seem to get the proper sequesnce of code to do what I need it to do. I cannot insert an excel object as the external users do not have access to our file server. Any assistnace offerd will be greatly appreciated
