Sub problems

What exactly do you want to achieve? What syntax are you trying? What happens?

Before we know what you're trying to do, it's really hard to tell you what you should be doing differently.

I’m trying to make faders with red green and blue one with blue one with green and one with red but they keep overriding each other and I don’t know how to fix the problem I’ve watched the videos but they still keep overriding each other what I do is going into sub select the sub I want then I select the lights I want then I select the green and blue and null them. I then go to test the sub but they still over ride each other

There are a couple of videos out on this topic, the one I found offhand was at:

But I also think there is an official ETC video out there as well.

The basic gist is that you're probably recording all color values into the sub, instead of just the single color emitter that you're wanting to record into that sub.
