    This is exactly what my proosed dax is doing. To eliminate the problem of the first row please try

    Calculation =
    VAR T =
    ALL ( 'All Web Site Data (2)' )
    VAR InService =
    MAXX ( T, 'All Web Site Data (2)'[EBS IN SERVICE] )
    VAR Result =
    SUMX (
    FILTER (
    T,
    'All Web Site Data (2)'[Date] <= MAX ( 'All Web Site Data (2)'[Date] )
    ),
    IF (
    'All Web Site Data (2)'[Date] <> BLANK (),
    'All Web Site Data (2)'[Column1] - 'All Web Site Data (2)'[Column2]
    )
    )
    RETURN
    InService - Result

    Why have you ignored the first 3 rows of [Trucks Available] column (6, 14 & 4)?

    tamerj1  , Sorry I i should have a starting time that everthing is defulted to zero to get the correct calculations. 

     

    Lets start at 0300 ( no truck sign outs happens then)

     

    Please see example how to calculate from the value 90 :

    tamerj1 , this works, but I belive the caluclations crew up because of the times from 0000-0200. Anyway to start this from the Time 0300 ? I belive this would slove this issue.

     

    Thank you so much again

    tamerj1 , seems to be calculating correcly but the value is starting at Zero instead of the actual value, like the one we had before, (90) . Thanks again
