    mgrayTCB try this:

     

    MS Months Chg2 =
AVERAGEX (
    FILTER (
        ADDCOLUMNS (
            Project,
            "@datechg",
                VAR SSdate =
                    CALCULATE ( MINX ( MilestoneSS, MilestoneSS[DateActOrEstSS] ) )
                VAR Curdate =
                    CALCULATE ( MAXX ( Milestones, Milestones[DateActOrEst] ) )
                VAR datechg =
                    DATEDIFF ( SSdate, Curdate, DAY ) / 30.4
                RETURN
                    datechg
        ),
        [@datechg] <> 0

    mgrayTCB no problem.

    Please also add calculate on top of minx and maxx in lines 7 and 9 and you can actually remove the calculate we added before, it has no meaning. All there is vars anyway.

    BTW, in general, you don't need the calculate in line 2.

Thank you so much! I was wondering about performance and before I could even test it in my model you rewrote it. I have never seen the "@" syntax. Is that just your convention for columns of virutal tables?

thanks again!
