I’m building a website in **Wix Studio** and I have a CMS collection for animals.  
Each item has a date field called **“geborenam”** (date of birth).  
On my **List Page** (“Tiere alle”), I want to display the **calculated age** of each animal in the format:

**“X years, Y months”**

I already have a text element inside the repeated list item where the age should appear.

My problem is:

- Wix Studio CMS does not support calculated fields

- I cannot get the Velo code working on the List Page

- I am unsure how to correctly use the **itemReady** function in Wix Studio

- I need the age to update dynamically based on the current date

Can someone please explain:

1. Where exactly the **Page Code** is located in Wix Studio?

2. How to correctly use the **itemReady($item, itemData)** function for a List Page?

3. How to insert the birthdate (`geborenam`) from the CMS and convert it to age?

4. How to output the result into my text element (ID: `agetext`) inside the repeated item?

Any help or a working code example for Wix Studio (not the old Wix Editor) would be greatly appreciated.

Thank you!
