writing a recursive function

So I have this function...

=IF('Equipment List'!N2=TRUE,'Equipment List'!A2,"-")

and now instead of displaying "-" when it fails, I want it to check the next item in the list, 'Equipment List'!N3 and display it, A3.

Now what I can't figure out is that if N3 also fails, how can I get it to keep moving down the list till it finds an item to display or reaches the end?
