Access parameters in a configuration using this syntax:

```yaml
"[parameter('<parameter-name>')]"
"[parameters('<parameter-name>')]"
```

In YAML, the parameter syntax needs to be enclosed in double-quotes when used as an inline value.
If the syntax isn't quoted, YAML interprets the syntax as an array.

```yaml
valid: "[parameter('example')]"
valid: "[parameters('example')]"
# This unquoted syntax:
invalid: [parameter('example')]
invalid: [parameters('example')]
# Evaluates to this YAML:
invalid:
- parameter('example')
- parameters('example')
