Formula challenge - 2D lookup and sum

The problem The data below shows cups of coffee sold at a small kiosk for a week at different hours of the day. The times in column B are valid Excel times. The challenge What formula in cell I5 will correctly sum the total cups sold after 12:00 PM on Tuesday and Thursday? Relevant cells are shaded in green. For your convenience, the following named ranges are available: data = C5:G14 times = B5:B14 days = C4:G4 Download the Excel workbook, and leave your answer as a comment below. Constraints Your formula should dynamically locate the cells to sum, without hardcoded references. In other words, =SUM(D10:D14,F10:F14) is not valid. Use named ranges when possible to make your formula easy to read.
