AMORT grouping param not working

[mainakae]

Hello all!

I've been trying to store the amortization results of the Finance application somewhere, but couldn't find a way to do so, so after a quick search I found the AMORT command for the spreadsheet application. Unfortunately, I couldn't make the "grouping" param work: I'm trying to get all the monthly payments instead of yearly sums. Seems to fall back to grouping=ppyr no mather what you introduce.

Great calculator and great forum!
