Math Formula ?

Hello,
I look for a formula to calculate the difference :
Column IG ==> taking in account the name and the date.


An idea ?
Thanks

Is your entire dataset configured like this, i.e. pairs of names with descending dates?

You can do this with a simpler workflow by using the Column Expressions node.

Sorry. Here’s an even simpler workflow with just a Column Expressions node. I had its misconfigured in the last post. I output a string rather than an integer column.
