# Managing Targets

**Important rules to keep in mind when working with targets:**

<p class="callout danger">1. The code cannot contain any punctuation. The only exceptions allowed are an underscore (**\_**), an ampersand (**&amp;**) (to add two or more codes in one target), and an exclamation mark (**!**) (for negative targets).   
  
2. Using a '-' will cause problems in the backend (rotation file) once the target is used in a booking  
  
3. Targets have a character limit of 40. If a single target would exceed 40 characters, consider using [advanced targeting](https://documentation.adhese.org/books/inventory-management/page/advanced-targeting)).</p>

To manage targets in Adhese, click the *Targets - Manage targets* link in the administration screen. The following screen is then displayed:

The screen is divided into two parts:

- Select target types on the left side
- Add new target values on the right side

The **Select target types** part shows all the available target types and indicates whether they are editable or not. Ticked boxes are editable. Empty boxes are not editable. When you select a target type, the colour changes from yellow to orange, and your selection is displayed in the *Add new target/target values* part of the screen.

Click **Add new target** if you want to add a new target value. To add a new target, fill in a name, give it a code and hit the *Add Target* button.

The code has to be unique to be accepted by the application.

- a search box
- a back and next button showing the number of pages for this particular target
- a checkbox to hide or show inactive entries.

The list can be sorted by clicking the *\#*, *name* or *code*.

You can edit the name of each target. After editing, you can save your changes by clicking the *save* button.

To deactivate a target, simply click on the *deactivate* button. Once deactivated, the button's label will change to *activate*.

To find out more about how targeting can be used within a booking, see the [Targeting](https://documentation.adhese.org/books/campaign-management/page/bookings#bkmrk-targeting) section of the **Bookings** page
