IF statement unexpected result evaluation

[dgwilson]

The goal here is to remove a very tiny piece of hard coding so that this measure never needs to be touched again. The measure returns a year to date sum on revenue.

It works if the year is hard coded.

It does not work if the year is another measure. I can with certainty say that the measure [Fiscal Year TY] is returning 2019 as a Whole Number.

I'm seeking recommendations on what I should do next.

_Revenue TY =

    VAR reportMonth = [Report_Month]
    VAR fiscalYear = 2019                        // this works and is returning a value that charts correctly on a line graph (July, August, September)
//    VAR fiscalYear = [Fiscal Year TY]           // returns the value (total) – it does not chart on a line graph (only shows a “dot” for the last month).

RETURN
CALCULATE(TOTALYTD(SUM(EVO_DMT_BUS_CUST_PROFIT_VW[_Revenue]), 'Calendar'[Date], "30 June"), 'Calendar'[Fiscal Year]=fiscalYear, ALL(EVO_DMT_BUS_CUST_PROFIT_VW[RPT_MONTH]), EVO_DMT_BUS_CUST_PROFIT_VW[RPT_MONTH] <= reportMonth)

The results I am receiving are below (the aqua line shoudl be ignored - that's the previous year and another (similar) calculation.
