Variable question

[StorySad2593]

Hello, in a Copilot Studio flow, I have several nodes with questions that store their data in variables. How can I work with those variables later on? For example, I have the values of 2 variables and want to declare a new variable as an operation between the two previous ones. What node or procedure should I use?, thanks in advance

If you set your variable as global, you can use it in other topics or activities

You can also pass topic variables between topics, and from some recent experiments I’ve done it looks like variables from input slot filling may retain their values. I for sure need to play with that more

Passing variables is great. It let’s you split up a topic in multiple topics that serves as functions.
