I’m using dolibarr 18.0.1 on apache ([all-inkl.com](http://all-inkl.com)) and mariaDB, php 8.1.

The following variables do not work in my email templates:  
**PROJECT\_ID**  
**PROJECT\_REF**  
**PROJECT\_NAME**

So, when using any of these variables, the email message body just insert their key, e. g.

The expected behavior would be:  
**PROJECT\_ID** =\> PJ0815-MyProject-ID

Does anybody know how to make this work?

best,  
Mikee
