## How to Use the MonthName Function in Report Custom Columns?

In this tutorial, we’ll learn how to design expressions using the `MonthName` function within the reporting grid to display the **month name** from a date field like *Bill Date*.

***

### Accessing the Expression Designer:

* Navigate to the **Reporting** section.
* Open the **Sales Register Detailed Report** or any **"Report".**
* Go to **Setup Column Attributes**.
* Here, you'll see a list of available columns that can be used to build expressions.
* Click on **"Add/Edit Expression Columns"** where you can write your expression using predefined functions.

* Before adding the expression to the report, go to **Other Settings**.
* Ensure the **Script Editor** is set to **VBScript**.

* Click **Save**.
  * *Note: VBScript is the default for new configurations but always verify this setting.*

### Writing Your First Expression

* Every expression must start with the script header: **'#@LSCRIPT**

* Click the (+) Plus icon to create a new expression.
* Fill in the required fields:&#x20;
  * **Expression Name** – A unique name for your expression.
  * **Expression Type** – Choose either **Text** or **Numeric** depending on the expected output.

### Creating a Simple MonthName() Expression

* Double-click your newly created expression to insert it into the script editor.
* Define the expression using the syntax:
  * Expression Name = MONTHNAME(CDATE(BILL\_DATE))
  * `CDate(BILL_DATE)` converts the bill date string into a proper date format.
  * `MonthName(...)` extracts the full name of the month (e.g., January, February).

* Save the expression once defined.
* Scroll down and **check the box** beside the expression name to enable it.

* Save and proceed to check the effect.
* **Refresh the report** to view the final result.

### Result:

The newly added column will now display the **month name** based on the *Bill Date* field for each record.
