How to find second to last non blank value in a row excel

Question

I have data in Y:AI, and return the last non blank value in AJ

I return the last value in AJ3 for example, by using:

=LOOKUP(2,1/(Y3:AI3<>0),Y3:AI3)

I have tried two different ways to return the second to last non blank value.

=LOOKUP(2,1/(Y3:AI3<>AK3),Y3:AI3)
=LOOKUP(2,1/(or(Y3:AI3<>0, Y3:AI3<>AJ3),Y3:AI3)

The first case returns the value in AI, the second case returns either the value in Y, or a #DIV0! error.

Any help in this would be greatly appreciated.

An offline friend managed to help me out!

The second case was a poor attempt at ensuring the cells aren't blank.

The correct way of doing this was:

=LOOKUP(2,1/((Y3:AI3<>AJ3)*(Y3:AI3<>"")),Y3:AI3)

All solved now! :)
