After right-clicking anywhere within the **Parameter** list pane, a pop-up box with **New** and **Edit** will appear.

Select **New** to bring up and open the \<New Param> window for completion.

## Fields

| Field Name | Description |
|---|---|
| Code | The **ID** name of the field. Forced to uppercase. |
| Description | Description of the field supplied in the **Code** field. Tab into this field to erase the prompt, else your description will be amended to the end of the prompt. |
| Type | Field type such as string or integer. Select from the available drop-down list. |
| Value | The value assigned to the field, as specified in the **Code**. |

## Buttons

| Button Name | Description |

Once created and added, the **Parameter** will display in the list.

And once created, the **Parameter** will be accessible for inclusion only in the script for this **Map**, by either dragging from the local **Parameter** pane or by typing it directly into the script, such as the example below which shows any local **Map Parameter** and any global **Parameter**.

When using a global **Parameter** in a script, the parameter is identified in the **Map** script by prefixing the field name with P\_, such as P\_\<Parameter Group> as illustrated below.

Please see [Parameters](/statelake/administering-statelake/designer/global-setup/parameters/) for more information about **Global Parameters**.
