SumByColor Macro...

[Murph]

I am using the following Macro - the formula I use to access the macro is

=sumBYCOLOR(C13:H22,3,TRUE)

The problem I am having is that the formula does not automatically calculate
no information inputted into the excel sheet. I have to go to the cell with
the formula and place my cursor at the end of the formula and hit enter for
it to adjust with the new information. Any help?

Macro is:Function SumByColor(InRange As Range, WhatColorIndex As Integer, _
Optional OfText As Boolean = False) As Double
'
' This function return the SUM of the values of cells in
' InRange with a background color, or if OfText is True a
' font color, equal to WhatColorIndex.
'
Dim Rng As Range
Dim OK As Boolean

Application.Volatile True
For Each Rng In InRange.Cells
If OfText = True Then
OK = (Rng.Font.ColorIndex = WhatColorIndex)
Else
OK = (Rng.Interior.ColorIndex = WhatColorIndex)
End If
If OK And IsNumeric(Rng.Value) Then
SumByColor = SumByColor + Rng.Value
End If
Next Rng

End Function

Hi Murph,

Try:

Tools | Options | Calculation | check 'Automatic'

And just to add, if you are just changing colors, no formula is going to
update until there is a calculate (which is not triggered by changing
colors).

 

[Dave Peterson]

Changing the color doesn't cause excel to recalculate.

You'll need to recalculate to make sure your values are correct.

Hitting the F9 may be enough.

Norman -

I checked that and it is selected currently.

I assume this basically has something to do with Excel not recognizing
colors as part of a formula argument. If I click in another cell and just
type in 0 and hit enter it then recalculates and finds the 'red' and 'black'
entries. Just seems odd - and of course not as user friendly as I would like.

Also if I delete an entry in the cell it automatically recalculates. So
basically the problem happens when I take the cell font color from black to
red.

Thanks for the help.

As stated by several people in response to your post, a color change does
not cause a recalculation to occur. (Excel does not inherently support
color as a discriminator in any type of calculation).

I modified the code a bit so a user can select the color by incduing a cell
range reference:

Function SumByColor(InRange As Range, rColor As Range, _
Optional OfText As Boolean = False) As Double
'
' This function return the SUM of the values of cells in
' InRange with a background color, or if OfText is True a
' font color, equal to WhatColorIndex.
'
' the user can select the color by including a reference to a call or a
range of cells
' of the appropriate color

Dim Rng As Range
Dim iClr As Integer ' the color to sum
Dim iCellClr ' the color of the cell
Dim OK As Boolean

Application.Volatile True

If OfText = True Then
iClr = rColor.Font.ColorIndex
Else
iClr = rColor.Interior.ColorIndex
End If

For Each Rng In InRange.Cells
If OfText = True Then
iCellClr = Rng.Font.ColorIndex
Else
iCellClr = Rng.Interior.ColorIndex
End If

If IsNumeric(Rng.Value) And iCellClr = iClr Then
SumByColor = SumByColor + Rng.Value
End If

Next Rng

Application.Calculate

End Function
