Vlookup to subtract values across worksheets

  • Good Day,


    I have a workbook were I pull reports for a previous day and a running total for the current day on 2 separate sheets. I need to workout the difference in order to get today's figures on a third sheet. The names however are not in order on the 2 sheets. Would you use Vlookup formula and can you point me to the right syntax to work out the difference between the values corresponding to a particular name in the sheet "Current Day Total" & "Previous Day Total".


    Appreciate your help.


    Best regards


    Rob

    A couple of questions:


    1. Are these names unique values?
    2. Is there integrity across the sheets regarding the spelling of those names?
    3. Will the position of the tables being referenced move at all? (Hopefully not!)
    4. What is the calculation you want to perform? Is it current - previous or previous - current?

    See if this does what you want. In C2, copied across and down:


    Code
    1. =IFNA(INDEX('Previous Day Total'!$C$2:$E$12,MATCH(Daily!$B2,'Previous Day Total'!$B$2:$B$28,0),MATCH(Daily!C$1,'Previous Day Total'!$C$1:$E$1,0)),0)-IFNA(INDEX('Current Day Total '!$C$2:$E$9,MATCH(Daily!$B2,'Current Day Total '!$B$2:$B$28,0),MATCH(Daily!C$1,'Current Day Total '!$C$1:$E$1,0)),0)

    Hello Ali.
    Unfortunately I am getting an invalid name error (#NAME?) with the formula.


    1. Are these names unique values? Yes
    2. Is there integrity across the sheets regarding the spelling of those names? Yes
    3. Will the position of the tables being referenced move at all? (Hopefully not!) No
    4. What is the calculation you want to perform? Is it current - previous or previous - current? current - previous

    Try this instead:


    Code
    1. =IF(ISNA(INDEX('Current Day Total '!$C$2:$E$12,MATCH(Daily!$B2,'Current Day Total '!$B$2:$B$28,0),MATCH(Daily!C$1,'Current Day Total '!$C$1:$E$1,0))),0,INDEX('Current Day Total '!$C$2:$E$12,MATCH(Daily!$B2,'Current Day Total '!$B$2:$B$28,0),MATCH(Daily!C$1,'Current Day Total '!$C$1:$E$1,0))-IF(ISNA(INDEX('Previous Day Total'!$C$2:$E$12,MATCH(Daily!$B2,'Previous Day Total'!$B$2:$B$28,0),MATCH(Daily!C$1,'Previous Day Total'!$C$1:$E$1,0))),0,INDEX('Previous Day Total'!$C$2:$E$12,MATCH(Daily!$B2,'Previous Day Total'!$B$2:$B$28,0),MATCH(Daily!C$1,'Previous Day Total'!$C$1:$E$1,0))))

    Hello Ali


    I am using Excel 2010.


    The 2nd formula does work but gave erroneous results. i.e. Donald would have 2 points (11 on 'Current Day Total' - 9 on 'Previous Day Total')

    Thank you so much

    I think you might have copied and pasted the formula before I reposted it with a correction - could you try again, please?
