I tried this formula after changing the cells to make it fit my spreadsheet,
but it didn't work. It gave an "N/A" as the output.

6700 rows deep x 50 columns wide

If Job 5 takes 1 day, Job 10 takes 1 day, Job 25 takes 3 days, etc what's
the easiest way to sum the total number of days for each part? I could do it
manually, but I don't want 50 sub-calculations in my formula.

Well, if the jobs always have the same time, based on job number, this
should work. Set up your jobs/times in a simple database somewhere,
say in Sheet2, A1:B100, sorted in numerical order. Start with a 0 - 0
job - days item. So:
0 0
5 1
10 1
25 3

Then this formula should work:
=SUMPRODUCT(B2:AY2,LOOKUP(B2:AY2,Sheet2!A1:B100))
