I know there's an issue with objects not being recognised immediately after they've been created if on the same event-level (the bane of my C2 life), but this appears to be something else.
I need several listboxes. I'm creating 2 and giving them a variable 'Number' to identify them. I then try to identify each and add an item. The first isn't recognised and doesn't respond, but the second does. They're both one sub-level below the creation and on the same level. Is this a C2 thing that I don't know about, or am I doing something very silly? I've attached the code below, have stripped it of everything except the basics. Listbox0 here doesn't respond (if I put a sound in that section it doesn't trigger for example).
