Events + Chat Plugins

Hello, I would like to implement your plugins Events+ and Chat into our sites. I like the way you have done this with live support. I would like to know how i should configure the plugins to have the same functionality and and work flow that you have done here in the live support tab. I am having trouble with the source id and target portion of the events plug in settings.

I am getting this error on the top of the admin screen, even after creating dedicated pages. This is not a valid source ID.
