Hello, 

I created a field called "Public tarification" ("Tarif public") on the inventory, for the different products.

I created a column in the SO called "Public price" and i would like to like it with the "public tarification" so the value written on the product description in the inventory appears on the SO. 

As you can see, when I try to save, I have an error. I can't get what is wrong, does anyone have an idea?

Thank you,

Camille
