using this formula AVERAGE(IF(B9:D9<0,B9:D9,"")) the result should be
5022.5. This is what is shown when i click on the function bar to look at the
formula but on my spreadsheet it gives me and error #VALUE. Do you know why
this is?

Your formula should work just fine as an array formula. Commit it by
pressing Ctrl + Shift + Enter, not just Enter.

Here is a slightly simpler version:

=AVERAGE(IF(B9:D9<0,B9:D9))
