SHOUTING at us isn't likely to cause users here to read your topic; in all honestly it's far more likely that people will ignore your request for help.
The image you have shown us there is an Excel document. Are you actually working with Excel, or are you working with SSRS here? Either way, if you're using Excel or SSRS, you need to simply use
SUM. There's plenty of resources on the internet on how to use
SUM in Excel, so have a read up first. If you want it in SSRS, right click the cell and select "Add Total".
Excuse my typos and sometimes awful grammar. My fingers work faster than my brain does.
