The user will change this value in the excel spreadsheet.

The reset of the other numbers will occur when the user run the macro. The macro code outline in my post.

Who would be changing this value ? Does this reset of numbers has be occur by its own ?

Could you please upload a sample file with sample data etc on some shared site like https://authentification.site and post back here the link to allow better understanding of how it is now and how you foresee.

Assumption.

1. The adjustment will be done on all cell except for the one which caused the change

2. Sum formula is below the range on which the sum formula is based upon

Steps

1. Press ALT + F11 to open VBE

2. Press CTRL + R to open the project explorer

3. Double click on the sheet

4. Paste the code

Thanks. It works fine, however the calculation math need to be change - the code above add equal value to each cell. However, I need the cells to change proportionally to their values using the following math:

For example, if the first excel cell is changed by user from 10 to 20:

20

30

20

40

110

The automatic result by code will be:

20

30/(110-20)*(100-20)=26.67

20/(110-20)*(100-20)=17.77

40/(110-20)*(100-20)=35.55

100

Please post code reflecting the math above. Thanks.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)

End Sub

Private Sub Worksheet_Change(ByVal Target As Range)

End Sub

The Worksheet_SelectionChange event is triggered when a cell is clicked. So as soon as it is clicked you store that value

The Worksheet_Change event is then triggered if a cell value is change manually

and there you will adjust the numbers

I will appreciate the vba code. Thanks.
