[RyinntheDK]

Hello all!

I'm about 3 hours in to my first attempt at creating (err, finding one and building on to it) an addon. I found an addon that I thought was a good start, but lacked a lot of what I desired, so why not learn LUA and write my own eh?

What I've had a tough time doing is creating a toggle effect when using slash commands + Msg.

As you can see in the code, if Msg == "on" then I CreateFrame. If Msg == "off", essentially I would like to just undo the CreateFrame that I just created. I can't figure out how to do this without just applying a ReloadUI (as you see commented out), which, while effective, rather annoying.

Any help would be much appreciated!
