Automation of scripts with random value

[emiliel11632823]

Good morning all,
Technical question concerning the automation of scripts in Photoshop.
I created a script. In this script, I created a gradient transfer curve, with a random gradient. So far so good.
Normally, when I click on this random button, I have a different gradient each time. But by creating a script with this click on the random button, it saves the ID of the gradient. Suddenly, during a mass automation, it is always this same gradient that comes out.
I'm not sure I'm very clear, am I clear? 😁
So in the end, how do you create a script, with a gradient that changes with each repetition of the script (therefore really random)?
Thank you and good day !

Edit: I hadn’t grasped the 10 places correctly, the multiplicator was one zero short …

Great !!! Thank you so much/

Jut one little thing. It's correct for a random "gradient". But what-s the code for a random "gradient transfer curve" ? (I'm not sure it's the good term, I'm french, my photoshop is french, and in french it's "une courbe transfert de dégradé")
