Hi all, how can I use multiple arguments in the IF formula?

So I have this spreadsheet with responses from a Google form.
I want column I to be filled in only when it is a different input than the standard countries they get to choose from.
How can I do this?

thank you in advance!

=IFERROR(IFS(A2="The Netherlands","",A2="Belgium"," ",A2="Germany","",A2="Great Britain","",A2="Poland","",A2="Switzerland","",A2="Austria",""),A2)

Could also do IFSNOT but this is easy enough to have the error copy it.

I believe this is what you are asking but the spreadsheet and information you provided was very confusing.

Using =IFS may be what you need, allows for multiple criteria.
But your file is not very clear what you expect.

Can you Provide expected result sample in the file?
