Hi,

I have excel files.

There are different sections in this file.

There are different features under each section.
Unequal weights are available for these features.
The sum of each section is 10.
However, if there are no features under a section, the weight of the non-features needs to be proportionally distributed to other features existing under the same section.
How can I do this with VBA.
First I set all the features and weights by default. Later, if the cell were written "No" in the column next to the no features, I thought it would be necessary to re-distribute the weight in this section.

But I could not .

As sample data

thanks your reply @wideboydixon

Excellent.
I've been trying to find a solution for about a week.
It's exactly what I want.

Could it be that we wanted to reduce the number of columns and be more efficient with one column?

Default Weights can not be changed. Constant values.

Can we make the table like this?
If it does not bother you, it will not take much time.

Could it make more sense if all the calculation / control is done in the weights column?

Default weights assigned to a two-dimension(Nbr,Default weights) and then
If do the operation above you can be less column and effective?

I appreciate your will and your knowledge.

I think I told you the last time I misunderstood.

If I try to tell you this way.First the C column (Weight) will be empty.

Sheet1​
After the user opens and writes the cells "No" in column C, calculations will be made.

When I saw the code you wrote, the logic came as follows.

I thought that when I run the code with the trigger(With Worksheet_change) when there is a change in column c,

when I write "No" for cells in column c, Recalculation is done.

Let's say I wrote first "No" after a certain period of time this feature provided and I will delete "No"

Doesn't make sense this way. How can you weight the features with no reference number to start with?

Hi wideboydixon ;

Click to expand...

is it be possible in the following way?

1. Column Nbr and default weights are initially defined as a row constant or array(Nbr,weights).

2.Then, if there is "No" in the weight column, we will write the default weights to the weight column by matching the first item in array(Nbr,weights) with the column Nbr.

3.later,If weights are written when the end of the section is finished, The new weights are calculated for the end of the rewrite weights.

What will be the benefit or activity of process.

The user will not have to know all the weights beforehand.

The user will only write "No" when the feature is not available.

The user will be able to change the "No" has previously written.

The user will be able to change the status of an existing feature.


With all respect
