Sum data across crosstab query

[jwillet1]

I have a crosstab query that I would like to sum data across. Each row is a seperate experimental product, and each column is a test phase that each product goes through. The data is the number of days each product was in each test phase. What I need is the sum total of days that all products were in all phases. Think of this table as a single item, and each row is a slightly different version of the item to test. So what I need is essentially how many days this item has been in testing across all variations.

Thanks for the help.
