Unfortunately I also tried adding the type too like so, since the script permits it :

InvList {TG:My Container} +ingot/deuteriumcontainer:1000

But it didn't work. I'll try againt to double check any typo I may have made.

And thanks for all the help.

Alright here's the explanation (shout out to Kham on MMaster's Auto LCD, he helped me a lot).

So the thing is any modded item that's not registered inside the script won't show if there's no specimen of it in the cargo. As long as there's one item of it in the circuit a line will appear on the LCDs. There's a smallish tweak to the script to make the items show even when there's zero of them.

@Moss

Kindly, share that tweak, for future reference.

Huh.. I don't remember what it was. Let me think on it and I'll get back to you.
