**Tip:** The colon : in the command signifies where a placeholder variable should be added for an argument, it is not a literal part of the code. For example, a real response might appear as:
```javascript

}
```
Note "namedmap_tutorial" is the variable that was used in place of the "template_id". See the [Named Map Tutorial](http://docs.cartodb.com/tutorials/named_maps/), from The Map Academy, for more information about this specific example.
#### Placeholder Errors
As developers use many different methods to input placeholder variables, you may find placeholder examples with other symbols such as, <template_id>, {template_id}, $template_id, or @template_id; indicating that a placeholder variable should be added. If an error is raised, ensure that your placeholder variable appears without any added symbols.
