Your syntax is incorrect.

It looks like this:

Optionally, if relevant for your language and it is configured, there can be additional plural forms after "TO-DISPLAY-FOR-PLURAL".

Your translation should probably look something like:

NaN $1 eellissa cirjaussas

Which roughly translates back to:

NaN $1 previous resultss

Does that help?
