# Finding and fixing errors

Select an editor error to jump to the affected source. Unknown names are rejected: remove `typo` from this example and add an output before saving.

```xml
<report typo="yes">
  <outputs>
    <output name="names.csv" format="CSV" storage="DATABASE" dataset="customers">
      <columns><column>name</column></columns>
    </output>
  </outputs>
</report>
```

Alignment must be `left`, `center` or `right`; replace `diagonal` here.

```xml
<pdf><text align="diagonal"/></pdf>
```
