I'm looking do create a calculated field that looks up a certain year expenses and returns only the expenses on that year in the measure.

Here is my viz so far:

My Budget and Totals are correct but I'd like to find a way to include Year 1 and Year 2 expenses. For example, if year 1 is '4' and year 2 is '5'.

My data is listed as:

So I'd like to have the field for Year 1 to lookup Month that equals '2018-12' and return the 'Cumulative' which is 4.

My logic is to:

1 - Create a Parameter 'Year 1'

2 - Create Calculated Field:

       IF [Parameters].[Year 1] = ATTR([Month]) THEN SUM([Cumulative]) END

This doesn't work for me which I thought was correct from watching tutorials.

How could I make changes to the calculation where I went wrong?

Any help would be appreciated!
