trying to do a "countif" with multiple ranges and multiple criteria. Countif, Sumproduct?

I have a spreadsheet I use to track how I spend me time (attached). Here is a quick overview of how it is set up:
Summary Tab has a place where I can type in the categories of how I spend me time, which are to be tracked.
Mon-Fri tabs along the bottom are where I track each day. there are list drop down options for each 30 minute segment. the list is populated from the list typed in on the summary tab.
The bottom of each day totals how much time I spent in each category (I broke Monday).
I am trying to add a "priority" also, based on the good old Stephen Covey "important/Urgent" grid. See Tuesday for this.
I set up a drop down selection for "priority" in Tuesday, which pulls from column "i" in the summary tab
I'd like it to be totaled accord to priority and category per day. This is so I can look at the category and see what priority i am giving that category, or vice versa. In other words at the bottom (See Tuesday row 52 columns d-g...I tried to do this in E52, but it didn't work.

Would love some help on this! Thanks in advance!
