Calc YIELD() function, Error 502

[JeanneMarie]

I’ve got a spreadsheet with 6 columns and near the bottom of each are formulas like this, which work fine in five columns:
=YIELD(J4,J5,J6,J7,J8,J9,J10)
But now, this formula is displaying Err:502:
=YIELD(K4,K5,K6,K7,K8,K9,K10)

I’ve re-checked the data types of the arguments. (The first two are dates [Default English USA] and the rest are numbers/general.) And I’ve fiddled with the dates just to see if anything changes.

I’ve re-set my user profile, installed the latest ver. 24.8.6.2(x86_64), and rebooted the machine (Windows 11 Professional).

I’ve just copied the last two columns (J & K) into Columns L & M with the same result. L is okay and M has the same error. I’ve also pasted all columns into a clean, new spreadsheet. No help. The last column has this error.

Can anyone suggest what is going wrong and how to fix it?

Many thanks.

Nobody can tell without seeing the actual spreadsheet (not a screenshot).

Thanks so much for such a quick response. Spreadsheet attached.

Avoid date formats with 2-digit years. The date in K6 is 1935-02-27.

4 digits didn’t help, but I missed that 1935 tho I’ve noticed this problem before. Have to figure out how to prevent this in the future. THANKS x 1000.

EDIT: Obvious solution is to not use two digit years. Thanks again.
