# Does Not Match Regular Expression

**Introduction**

The "Does Not Match Regular Expression" step checks whether a variable does not match a specified regular expression and returns `Yes` if the match fails. This step is useful for validating that a variable's value does not conform to a specific pattern.

**Configuration**

* **Variable**: The text variable to be checked.
* **Value**: The regular expression to compare against the variable.

**Outputs**

* **Result**: A boolean value (`Yes` or `No`) indicating whether the variable does not match the specified regular expression.
