## Step 5 - Set “Class” for Numeric Fields

**Note**: If you are using SQL, skip this step. Do *not* change the class of your fields. With SQL, Jasper will automatically set the appropriate class for each field.

*When you're importing data from a custom report, by default, all fields are read as **text** fields. You’ll need to tell JasperSoft Studio which fields are numeric by adjusting the “Class” setting.*

* Click the **Outline Tab**
* **Expand the “Fields” section** in your Outline
* Select all your Integer fields
  * Use control-click or command-click to select multiple fields at once
  * Do *not* change the `Student ID` field

Next,

* Locate the **Properties Tab**  
* In the **Properties** tab, set the appropriate “**Class**” of your numeric fields.
* Set **Class** for any **Integer** fields to **java.lang.Integer**

**Repeat** the process if you have any **decimal numbers** in your data.

* Set **Class** for any **Decimal** fields to **java.lang.Double**.

*Class field is case sensitive.*
