I'm working on a pricing tool that uses a single price per user until 30 people. After that it switches to a banded approach. In other words, once you hit 31 people you are charged for 40. So far I have a formula of:

=INDEX($D$36:$AP$41,MATCH(D9,$C$36:$C$41,0),MATCH( E9,$D$35:$AP$35,0))

It works up to 30 but then it bombs out after that. Any advice would be greatly appreciated!
