Parallelperiod syntax error

[MarnikV]

I'm trying to create a DAX measure for the previous month or year sales, but it keeps throwing the following error:

 

If I replace MONTH by YEAR it gives me the same error, only then it says the syntax for YEAR is incorrect. What's wrong here?

@MarnikV  Oddly enough, don't use all caps. Use Year and Month as YEAR and MONTH mean different things.

Maybe put ;Month instead of ,Month.

Can't believe I missed that... Thanks!

But now it doesn't return anything? Looks like the values of Total Revenue LY are null...
