Adding 40 to a number if the cell color is "blue"

Hello

Using Excel 2013 for Windows 2008.  

I would appreciate a formula that would add 40 to numbers in a column if the COLOR of the column is a certain color.  For example "Blue".

I assume I would need to add a column to receive the results of that formula.

So let's assume the original number is in b2 and the results should be put in C2

Thanks!

Insert a module with this function code:

Public Function CellColor(row As Integer, col As Integer) As Long
    CellColor = Cells(row, col).Interior.ColorIndex
End Function

Open in new window


(screen shot with the module)
Module
To determine the value of your color:
=CellColor(1,1)

and then the final if statment (assuming 55 was your color):
=IF(CellColor(1,1) = 55, A1+40, A1)

you can then apply it for all columns.  Note that if you change the background color you'll need to go to the reference cell and update it.

Hi Kyle

Is inserting a module the same as inserting a macro?

Not sure how to insert a module in Excel 2013.  but will dig around.  But if you get this please let me know how to do that.

Thanks

Easiest way is to hit alt + F11 in your workbook

On the project (VBAProject) right click -> insert -> MODULE
(NOT CLASS module)

viola.

Hi Kyle

Got the module f11 ok.

But not sure how to do the rest with the formula, adding 40 to the column.

The "blue" column in the attached sample is Column B  

You will see 3 rows are blue and 2 are red.  I only want the addition of 40 to be added to the blue rows in column B.

Can you help with the attached as your guide.

Thanks

Attached.

I updated the  function so that it can take a range:

Public Function CellColor(rng As Range) As Long
    CellColor = Cells(rng.row, rng.Column).Interior.ColorIndex
End Function

Open in new window


Again note that changing the color by default doesn't tell excel to update the formulas.  You need to update the value of A or reapply the forumla in column E.

Hi

Looks like it's working perfectly.  Give me a day to test it on some files and I'll get you the points.  I may have a question on the best way to keep that macro/module as part of my Excel so I can use it on other files.  It will ALWAYS be the same blue.  

(And some points to ihasham too for that useful link.)

Is this always for yourself?  Or are you wanting to publish it to others?

if you only need it for yourself you can use:
http://office.microsoft.com/en-us/excel-help/copy-your-macros-to-a-personal-macro-workbook-HA102174076.aspx


Essentially create a macro which creates a personal work book.  (Don't worry, you can delete it after).

Then put the code in THAT module 1 (the personal.xlsb).  

That should be available whenever you're on your computer.

Hi Kyle

Yes, it will always be for myself --- and I'll use that link to do that.

Looking good so far.  I'll be awarding points later today or tomorrow. :)

Hi  

I "always" will be using the attached cell color.  But I am having a problem getting the cell color formula to "work".

Can you double check the attached spreadsheet?

Thanks

I'm getting 23 for your cell color.  

Did you use the updated function?

Public Function CellColor(rng As Range) As Long
    CellColor = Cells(rng.row, rng.Column).Interior.ColorIndex
End Function

Hi

I will double check.  A little later today :)  And will make sure the updated function is in place.

Thanks

Hi Kyle,

I am sure this is so simple, but take a look at attached.  I've got things messed up.

All I am updating is the Replacement cost based on Year built.  

So if the Year Built cell is Blue (23)  (in column L)  then the "Replacement cost Per Sq Footage" (based on Column K) cell  will have 40 added to it -- results of the formula put in the Column M (Updated replacement cost).

It's exactly as you solution solved it, but in transposing it to my actual page, I've missed something.

I would appreciate your adjusting the attached excel.

Thanks

You had everything exactly right.  I'm wondering if the personal workbook wasn't applied for some reason.  I brought in the function for this workbook's module and it worked fine.
