When Subtracting Dates to get number of days it comes out as "4382"

I'm subtracting two dates in my document. But instead of the difference in days it comes out with a 43832 or really a date.



At one point it was working.

Check the format for Col R

The first argument of MATCH is usually a single value/cell, not an entire column?

Perhaps attach a file, trimmed down to a few rows in each table (which will still produce a value) to show the error and state the expected result(s)
