Using indirect in a match function to change row dinamically

Hi,

I would be grateful if you could help me with a problem I have when using MATCH.
How can I reference a row dinamically? I have it currently set on 7:7 but I would like to use a formula (indirect?) so that it changes according to the values of another cell:

Thanks a lot!

Try

=MATCH(C5,INDEX('v2'!$A:$XFD,ValueOfAnotherCell,0),0)
