This error message will be shown to anyone except the admins. The admins will see the detailed error message. Leave empty to use the default message.

This boolean expression is used to determine if this action will execute. Use it to enable or disable actions programatically. For example, you'd enable a ShowError action only if you've found an error let's say when you parsed a response from a web service. A common example is [HasRole:Administrators|true] or [SomeField] == "Some Value". This field supports My Tokens.

Actions below this line may never execute. Drag them above this action.
