Groovy - Read Only Using Dimension Attributes

Summary:

I am trying to find a way to get specific cells read only based on a combination of of an account value and a dimension attribute. It is working for the account value currently but I need to add the attribute logic as well. I am not very familiar with Groovy yet, and not sure how to best add new logic to the existing (highlighted below) that says that the Project dimension attribute of "Opportunity" must also equal "Salesforce" for the read only to initiate. Any help is appreciated.
