Thank you for the solution Darren, I did that actually , As it would need adding of another column I was wondering Would that be an ideal way or would there be any other way without having to add extra column?
I don’t know. I would need to look at every single column that feeds into that if-then-else column, and every single column that feeds into every single one of those, and so on, all the way back to the first non-computed column, and confirm that every column that is referenced in the whole chain is a number type. I don’t have the time or energy to lead you through that. But you’re quite welcome to have a go at it by yourself, it could be a good learning exercise.
To me it seems that you are using a comma separator in your initial math columns and the single value columns are keeping this configuration.
The if-then-else else column is changing the format of the number and removing the comma separator.
As Darren suggested, you could add a math column after your if-then-else column for the single purpose of reformatting your numbers with the comma separator. Ideally, the if-then-else column would keep the original formatting or have a number-formatting option, but it doesn’t yet.
