How do you make a task disappear in script builder

I made a project management app. However, I can't figure out how to do something:

I want to be able to click a "completed" decision checkbox and have the whole record turn red in the master view and disappear from other views. This is probably relatively simple, but after studying your documentation I cannot figure it out.

Seriously, Gentlemen, you really really need better documentation on the script builder.

Thanks,
