Applying a Condition to a Link
Keep the following points in mind when making a conditional link:
You can only add conditions to the links between explicitly linked variables. You cannot add conditions to the links between implicitly linked variables.
When drawing more than one link to the same target variable, make sure that the conditions assigned to each link are mutually exclusive.
