Select Shop, Format(DateSold,"mmm/yyyy") As YMSold,  Sum(IIf(All_Yellow_Cap_Sold = "Yes", 1, 0)) as SumYellow, Sum(IIf(All_Black_Cap_Sold = "yes", 1, 0)) As SumBlack,  Sum(IIf(All_White_Cap_Sold = "yes", 1, 0)), Sum(IIf(   All_Red_Cap_Sold = "yes", 1, 0)) As SumRed

Pat I need just mmm/yyyy grouping not Shops any more, I adjusted your solution it gives me column totals as first row but not proper numbers for mmm/yyyy rows just 1 or 0 in those rows. Should I use count instead sum??

I your suggestion I changed Sum(IIf(All_Yellow_Cap_Sold = "Yes", 1, 0)) with
Sum(IIf(All_Yellow_Cap_Sold = -1, 1, 0)) as I was getting error.

If they are checkboxes, thange "yes"  to True with no quotes.

Actually since they are Y/N fields rather than strings, do this:

Select Shop, Format(DateSold,"mmm/yyyy") As YMSold,  Abs(Sum(All_Yellow_Cap_Sold)) as SumYellow, Abs(Sum(All_Black_Cap_Sold)) As SumBlack,  Abs(Sum(All_White_Cap_Sold)), Abs(Sum(All_Red_Cap_Sold)) As SumRed
From YourTable
Group By Shop, Format(DateSold,"mmm/yyyy") ;

To omit shop:

Select  Format(DateSold,"mmm/yyyy") As YMSold,  Abs(Sum(All_Yellow_Cap_Sold)) as SumYellow, Abs(Sum(All_Black_Cap_Sold)) As SumBlack,  Abs(Sum(All_White_Cap_Sold)), Abs(Sum(All_Red_Cap_Sold)) As SumRed
From YourTable
Group By Format(DateSold,"mmm/yyyy") ;

True values = -1 and False values = 0 so just summing and converting to the absolute value "counts" the instances of true.

The Count() function counts instances selected so  if you were to change the Sum() to Count() all the values would be identical and would be the number of rows for the month/year rather than the sum of true values.
