Topic "Can't find "serial number" in the variable list" a message from Xavier Thomas

I dont'know if het is a bug or missing fonctionnality but, of I am blind, of there is no variable for the serial number in the macro.
I want to use it, for direct link to the driver of a computer on the site of the manufacturer.
For example : www.dell.com/support/troubleshooting/be/fr/bebsdt1/servicetag/[+serial_number] And you go direct to the drivers list of the computer.
