How to modify UDF into VBA Macro

[Feroz90]

Hi All,

The below UDF will make us to identify the positive and negative value if any value is split into multiple values.

Example, 100, -50, -50, -800, 200, 200, 200, 200

Can it be used in a single column to highlight the matching values.

 

[sijpie]

I find it quite hard to understand how the function currently works. Can you give an example on how it would be used, and what the result then is?

And with example I mean:
what does the input look like
Is it an array formula
what is the output

Hi,

I found this in below link, all i want is to identify all the matching values in the same column by highlighting in any single color.

Thanks

Ah, I understand.

The UDF function yourefer to looks in a list of values and highlights values that cancel eachother like 50 and -50. You are looking for something that would highlight 100 and 2 cells of -50 as the latter two will cancel the 100.

That will be a lot more work and definitely not doable with a formula. No doubt I could construct a macro to do this, but then for instance if all the numbers are in one list, the question is what needs to cancel what?

And also would the cancellation always be one way (100 and 2x -50, 800 and 4x-200, but not -100 and 2x 50) or would it be both ways? The latter i think is far too complicated, too many permutations. And are there any other things that can help decide on whether the cancellation is ok, like dates close to each other, or names of companies, etc.
