TIME FILTER error

Your brackets, operators, functions, or special variables were not selected from the Variables Panel.

Try selecting it again from the Variables Panel.

Alternatively, it is possible to type curly brackets like these {{ }} so that it ends up with a background color:

{{ ( }}
{{ / }}
{{ + }}
{{ = }}
{{ formatDate() }}
etc.

I also suggest doing this Make Academy, as it covers selecting brackets, operators, functions, or special variables from the Variables Panel.

Hope this helps! Let me know if there are any further questions or issues.
