 **Example Usage**
 Let's start with the aforementioned contest winner for a simple example. Lets say we start a contest for chat members, the first person to write the correct answer in chat to a riddle wins a prize, and we want to save the persons name for later. We could turn on a chat event (found in the events tab) that looks at each message sent in chat. We could use a conditional effect (more on those here: https://docs.firebot.app/v5/guides/conditional-effects) to see if the chat message matches the correct answer. If it does we could use a "Toggle Event" effect to turn off the chat event so it no longer looks at each chat message and a Custom Variable effect to save the event winners name. We would save the name of the variable as something like "contestWinner" the Custom Variable data would be `$user` because `$user` is a built in variable for Firebot and is the username of the person who triggered the effect it contains. Again, you can access built in Firebot variables using the `$vars` button that you can find in most input boxes. 
 
-Later we could then use `$$contestWinner` anywhere that we wanted to use the winner's username. For example we could also trigger a Chat Effect containing something like "Congratulations to `$$contestWinner` for correctly guessing the answer, they win today's prize of a castle in the sky!"
