I am trying to create a conditional statement with 17 IFs. I started needing
to do 11 Ifs. I got over the Excel limit of 7 by identifying a cell in the
last element of the first string of 4 IFs in which there was a further string
with 7 IFs. However I now need to expand this to 17 IFs. I tried the same
technique of creating a third string with 6 more IFs and identifying this in
the last condition of the second string. It didn't work.

Any ideas.
