hello, i need help, i would like to add automatically with the automated rules, specific attributes according to my products. I want to add the availability attribute with the pre-order value for products that already have the pre-order ribbon.

I've tested several combinations with studio, none of which work (sorry, I can't upload an image).

automatic rules:

-model: product
-trigger: on save
-apply on: when ribbon is pre-order
-action:
1. update product attributes > attribute has availability
2. update product attributes > Value by adding availability: Pre-order
3. update product attributes > Value > attributes has availability

thank you for your help

my version odoo is 18 with studio

thanks for any help if someone had a solution
