Specific Date range for projects

Hey David!! Here are some screen captures that I hope help: 

So Savings Project ID is the generic project and then we have Savings project ID 2 (for projects within that) All of our pertinent data comes from the Numerical Material #, in other words , the product SAP code. This is entered into a daily database as the product moves through manufacturing. I have made measures (in the measures column) that determines how much savings I am making from each project per 10 lbs or case of product. However, as you can seem the projects have a specific start and end date. I have a date table, but I need a DAX or some measure so that it only pulls the savings measure from the project ID start date to end date, otherwise it will pull indefinite amounts of data, because each project may or may not have a different start and end date. Each project runs for 52 weeks.
