Enforce Quantity Rule

How to build a rule to enforce quantities to match across multiple product selections in the checkout process.

Enforce Quantity Example:

If a quantity of 5 is selected for the first product, the add-on product must also have a quantity of 5.

Event on the Rule Set to trigger the rule: Quantity Changed.

IF:

Id = _____ ( or Name = ____ )

AND

Second Id = ______ (or Second.Name = _____ ) 

AND

Q1 does not equal Q2

THEN:

Match Quantity

 

Note: Each AND should be in a different tier. Logic checks tiers in reverse order on the backend
