IFS function not working
Hi experts, I have a subscription of Office 365 (in fact my employer has). I am working on a database using the IFS function. Everything works well, I save the work and set the file aside. After a while, if I reopen the file, the formula with the IFS function is substituted with "=_xlfn.IFS((LEFT([@FR],3)="101")...".
When the sheet updates the values, then the formula is not recognised, and if I re-write the initial formula (that is "=IFS((LEFT([@FR],3)="101")...") the formula is not recognised either.
This problem arose several times. I am not sure how I fixed it. Maybe I closed excel, or restarted the computer. What is sure is that it keeps occurring.
The table I am using is of about 5200 lines and the file size is about 7MB.
I am also syncing the files with onedrive.
In the past this syncing function caused me enormous problems as instead of updating the new files I worked on, the syncing kept downloading and substituting the new with previous versions - yet this is another annoying problem.
Thank you for your assistance.
Regards,
Damiano

I kept getting "N/A" in the output.
checked the help notes
"Remarks
To specify a default result, enter TRUE for your final logical_test argument. If none of the other conditions are met, the corresponding value will be returned. In Example 1, rows 6 and 7 (with the 58 grade) demonstrate this.
If a logical_test argument is supplied without a corresponding value_if_true, this function shows a "You've entered too few arguments for this function" error message.
If a logical_test argument is evaluated and resolves to a value other than TRUE or FALSE, this function returns a #VALUE! error.
If no TRUE conditions are found, this function returns #N/A error."Since I was comparing combinations of files looking for duplicates, there were frequently no "true" result.
IFS(C4 = C3,"DUP",C4=C5,"DUP")
if neither condition is true, you get "N/A"
So:
IFNA(IFS(C4 = C3,"DUP",C4=C5,"DUP"),"")
This solved it for me. Does this help?

malcolmwri , 7-years old question was why IFS() is not available in some version of Excel. As for yiour case I'd use
=IF( (C4 = C3) + (C4=C5), "DUP", "")that is slightly better from performance point of view.

Obvs. Was trying to show simplified example to explain why "N/A" appears. In future, won't bother.

Thank you for your reply.
The compute I work on initially had a Microsoft Office Professional Plus 2016 (by the way, I had discovered that the release was installed with a pirate licence that the IT service provider - now sacked - had sold to me as authentic).
The firm I work for, opted to purchase few licences of Office 365. I installed one of the licences and everything worked well for a while.
Last week, after writing on this forum, I checked and for some reason it appeared that the version installed is MSOffice Professional Plus 2016.
I tried to switch licence, but I did not work. I tried something more drastic: I uninstalled everything (MSOffice and all other software related to that: Skype, Skype for Business, OneDrive, all spellcheck plug-ins everything that I could recognise related to MSOffice) and downloaded and installed Office 365 from the website over the weekend using the licence .
The process went through well and I got the message of a successful installation. Nevertheless, when checking, there you go, the zombie MSOffice Professional Plus 2016 is there again.
Whilst this explain why IFS does not function, reveals another problem: I can't switch to another licence and I am not able to totally remove the MSOffice Professional 2016.
I am tempted to reinitialise the entire pc, but maybe you can suggest a more focused, less drastic solution to kill the zombie once for all.
thank you,
Damiano

You may try complete uninstall, that's option 2 here https://support.office.com/en-us/article/uninstall-office-from-a-pc-9dd49b83-264a-477a-8fcc-2fdf5dbf61d8. Uninstalling from Control Panel keeps some elements of the Office.
