[Handle] ... [/Handle] conditionally executes after the code in the current container tag or format file is completed or a [Fail] tag is called. Takes a conditional expression as a parameter.
Each [Handle] ... [/Handle] container is executed after all other code within the current format file, [Protect] ... [/Protect] block, or custom tag.

| Optional Parameters | |

| Conditional Expression | The conditional expression which is executed to determine if the contents of the container tag should be executed. |
To perform code if a specific error is reported:
Use the [Handle] ... [/Handle] tags. After a [Fail] tag is called, Lasso will allow each handle block within the current [Protect] ... [/Protect] tags to run. Each [Handle] tag can check the current error message to see whether it should run or not.
The following example performs the code inside the [Handle] ... [/Handle] block if an unknown error occurs.
[Handle: (Error_CurrentError) == 'Unknown Error']
