# Calculations (Grouping)

**Applies to:** Lasernet 9

You can use the **Calculation** tool to calculate groups of item lines in the Conditional Area.

Selecting the **Sum Group** option of the **Calculation** tool allows creating a new script rearrange that sums over all values of rearranges selected within a group. By default, the script rearrange is inserted relative to the last instance of the group.

![](https://cdn.document360.io/c831ef63-c6b3-48ee-b443-3e33644e4e2e/Images/Documentation/image-X6NDGSKO.png)

1. For the added line, set the following properties: the **X** position - **162.5 mm** and **Y** - **1 mm**, **Relative to** - **Bottom of group** and **Group** - **ItemGroupGroup**.

![](https://cdn.document360.io/c831ef63-c6b3-48ee-b443-3e33644e4e2e/Images/Documentation/1628083607869.png)

A line is added at the bottom of the group just above the subtotal.

1. To complete the design you can insert the total sum for the **Amount** column. To this end, use the **Text** tool to create a new text object. Edit the object properties by setting **Object type** to **Script**, **Format category** to **Number**, **Script** to **Sum(Amount)**, **Font size** to **18 pt**, the **X** position to **196 mm**, the **Y** position to **281 mm**, and the **Font type** to **Bold**.
