# Values

> The {words} a Jellyn Lab system fills in. Who used it, the server, the time, options, answers, custom data and what blocks made.

Write a value in braces in any block's words, like `Welcome, {user}!`, and Jellyn fills it in when the system runs. A value that a system can't have (one its trigger doesn't give) is refused when you save, so a typo never reaches Discord.

```text title="A message block"
Thanks for applying, {user.name}! You joined {server} on {user.joined}.
Reason given: {option.reason}
```

<Note>
  Values never ping anyone: mentions are turned off in everything Lab sends, so `{user}` shows as a mention without notifying them.

## Custom data

Variables your systems remember between runs, made under **Custom data** in Jellyn Lab:

- **Kinds**: text, number, collection, object, and collection of objects.
- **Scope**: the whole **server**, or one for each **member**, **channel** or **player**.
- Written `{var.name}`. A member variable needs a run that is for someone; a channel one, a run in a channel.

Change one with the **Set a variable** block; check one with **If / Else**.
