How to return single value from a column

Hi,

I’m new to Power BI. Using the sample data below I can determine Monthly Variance and MoM with Power BI measures. I can even return the Year To Date total.

Where I’m struggling is return Monthly Units for current month  (6/1/2022 below). I need to print it out as “Cur Month”  with formatting so I think I need to create a measure  like below – however that returns the Year to Date number.

"Cur Mon: (" & FORMAT(SUM('Monthly Units]), "###" )  & ")

I need to solve this without using a Date slicer, so does that mean using the DAX Filter function? 

Thanks in advance.
