You are using ContractSent inside saveCS button, but as per your code there are nothing inside the ContractSent.
Instead of updating ContractSent try to update listOfContractSent.
Let me know if its work for you.

Thank you Mehul, I will give this a try.
Will this allow me to update just a single record however, or will it update all opportunities in the list?
