How to populate the value of Variable B based on the value of Variable A in a Harness.

Explanation:

Variable A:

The value of Variable A uses <+input> to allow user input.

allowedValues restricts the input to predefined options like Option1, Option2, and Option3.

Variable B:

The value of Variable B is determined dynamically based on the value of Variable A using Harness's expression language.

Logic:

If Variable A is Option1, then Variable B is set to ValueForOption1.

If Variable A is Option2, then Variable B is set to ValueForOption2.

If Variable A is Option3, then Variable B is set to ValueForOption3.

The else block provides a fallback value if none of the conditions are met.
