String Expression Problem

Hi everybody,

In Shop I'm trying to import random textures from one of my folder using the image node.
In the filename path I put this expression : "/Volumes/Vyking_Lacie/hdri/hdri/`round(fit01(rand($F),1,280))`.hdr"

This expression work fine but I want to had a global seed to the rand function so I tryed this expresion :

"/Volumes/Vyking_Lacie/hdri/hdri/`round(fit01(rand($F+ch("../../../GLOBAL_SEED")),1,280))`.hdr"
But I got an error and nothing is loading.

I tryed this path on some other node that have a filepath and it work perfectly, I only have a problem with this particular node.

Someone had this problem in the past?
