YTD same period last year when financial year runs July-June

[Anthony23]

Hello
I am trying to work out a YTD for last year when my year runs July-June.

My YTD for July-June is as followed:
Value Sale YTD:=TOTALYTD(SUM(Total[Value Sales]),Dates[Time],Dates[Time],"30-06")

And this seems to give the figures I require

But when I try:
YTD Last Year:=TOTALYTD(sum(Total[Value Sales]),DATEADD(Dates[Time],-12,MONTH))

It calculates the YTD from last year but Jan-Dec, and not the July-June I require.

Any insight would be great

Thanks
