Excel spreadsheet: Using a function in a sumif()

I have two columns in a worksheet: Class and Amount

Class     Amount
HW     $200.56
SW      $303.32
HW     $111.11
IN       $222.22
XX       $56.56
YY        $543.22

I have subtotals (using sumif) for each valid product class:
Hardware would be $311.67
Software would be $303.32
Installation would be $222.22

I want to have a subtotal for "Miscellaneous" that adds up all non-valid Classes.

I already have a IsValidProductClass() function. Is there a way to use that in a SUMIF funtion to total all invalid product classes?

GeriR,

In order to work with custom function, you should upload a sample worksheet so that we can look at how the custom function works to determine a solution for you.

You could add a column 'Valid class' and include only 'True' in the Sumifs.
Or you could have a separate sumifs using all  'do not equal' (ie: the opposite of current sumifs)

There's no way to call the function itself from within Sumifs and as Harry says without a view of the function no one can comment on how it might be changed.

You can also subtract all the valid sums from the grand total.

OK, I've attached a sample of what I am trying to do.

The workbook I'm working with is much more complicated.  

It is an order quoting tool that figures out all sorts of margins and profits and compares different types of pricing packages.

When my client is "finished" working on the quote, they want to be able to generate a worksheet for their customer showing only the quantity, prices, and product classes. They also want a subtotal box on the bottom. They want me to break out each of the valid product codes and then collect any invalid codes into a "Miscellaneous" box.

Unfortunately, their idea of "finished" is not quite final. They still want to be able to make minor tweaks.

So, I'm looking for a neat and simple way to create that box, and it has to still work if they then add or delete line items.

GeriR,

In you situation, I would say Saqib Husain, Syed's suggestion is the best.

Pretty much use the Grant Total subtracting all the rest.

=sum(b2:b19)-sum(B20:B25)

GeriR,

If you insist of getting your custom function to work in your formula, have to change your custom function to the following to make it accept range instead of only 1 cell.

Function IsValidProductClass(sProductClass As Range) As Variant
Dim OutputArr As Variant
Dim I As Long, I2 As Long

I = sProductClass.Count
ReDim OutputArr(1 To I)
For I2 = 1 To I
    Select Case sProductClass(I2)
    Case Is = "HW"
        OutputArr(I2) = True
    Case Is = "SW"
        OutputArr(I2) = True
    Case Is = "IN"
        OutputArr(I2) = True
    Case Is = "ES"
        OutputArr(I2) = True
    Case Is = "HS"
        OutputArr(I2) = True
    Case Is = "SV"
        OutputArr(I2) = True
    Case Else
        OutputArr(I2) = False
    End Select
Next I2
IsValidProductClass = Application.Transpose(OutputArr)
End Function

Open in new window

Then, in your sumif cell, you have to enter array formula
=SUMPRODUCT(NOT(isvalidproductclass(A2:A18))*B2:B18)

Open in new window

by Ctrl-Alt-Enter instead of Enter normally.
