I was using the accumulated interest for a CD. I was getting the ERR message so I recreated the example in the Help directory list for this function and it also created the same error message. I am using Quattro Pro Professional 2021. Any updates for this?
Click Insert -> Formula and use the formula composer (wizard).
The help uses this example:
@ACCRINTM(@DATE(89,12,15),@DATE(90,3,11),0.10,1000000,2)
The correct formula is:
@ACCRINTM(@DATE(1989;12;15);@DATE(1990;3;11);0.1;1000000;2)
Apparently, they changed the separator from comma to semicolon (at least on my system in Germany)
