Understand what condition sets are and how to use them.
22 / 143
means there are 22 conditions available in Condition set 1 out of 143 total conditions. Here, 143 is the total number of conditions available in all condition sets.
For example, here we are using the default Condition set 1, which has 22 conditions available, setting the rule to run if the Order total is greater than or equal to $50 and the Shipping country is the United States, since these conditions are available in Condition set 1.
For example, here we selected Condition set 3.
