I created the blueprint below to try and find the maximum value in an array of numbers, but I can’t figure out how to update a variable’s value.
Specifically, in the 2nd iteration, the value of max is -1 instead of 3.
How can I do so?
Thanks.

Hey @tal
welcome to the make community
You can use Numeric aggregator

You do not need so many modules.
Here’s an additional screenshot to show output of the **Numeric Aggregator** , as suggested by Manish:
You can also use the built-in function `max`
For more information, see the function documentation in the [Help Center](https://www.make.com/en/help).
