IF or SWITCH

Hi memarquez ,
Ran this through the Dax Formatter Daxformatter.com. Try it now, and if does not work, let us know what the output is.
Let me know if you have any questions. Remember if it finds a true as it drops through the tests, it stops and returns that value. You may want to break up the code into separate lines even if they have the same values. e.g (2) for readability and debugging.

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.
