I think the last one is messing you up but I don't think you need 3 checks. Just have - is not - and then leave the field empty. Does that work?

Hi @ericlung ,

how you can implement this in Flow Designer using JavaScript code:

1. Add a "Script" step in your flow after the array is populated.

var myArray = current.myArray; // Replace "current.myArray" with your array variable
var arrayLength = myArray.length;

​

• Add a "Flow Condition" step after the script to check if the array length is equal to zero .
• Configure the subsequent action to be triggered when the condition is true

@ericlung,

Your test results and Flow screenshot show different logic on the 3rd condition.   You're using OR, change to AND instead.
