Variable-related errors can occur for a variety of reasons. For instance, if you divide a variable by zero or decrypt using an incorrect key, then any operations you perform using that variable will not work and will generate empty values. To trap these errors, use the Variable Error match.

How to

1. Click Add Match.

2. Select Variable Error from the available matches.

3. Enter one or more user-defined variables.

4. Add behaviors to the rule to direct what happens in the event there is a variable error. For example, redirect to a sorry page or use Set Variable behavior to set a reasonable default value for your variable.
