    I am making an addon which when you use the slash command /cta the frame will hide and if it's hidden already the frame will show. Should be basic enough. However when I call MyFirstFrame_Frame:Hide() I receive this error:

    ``Message: [string "MyFirstFrame_Frame:OnHide"]:1: attempt to index global 'this' (a nil value)

     Time: 09/20/15 23:02:00
 Count: 1
 Stack: [string "*:OnHide"]:1: in function <[string "*:OnHide"]:1>

 Locals: self = MyFirstFrame_Frame {
  0 = <userdata>
  TimeSinceLastUpdate = 11.113000558689
 }
 (*temporary) = nil
 (*temporary) = nil
 (*temporary) = "attempt to index global 'this' (a nil value)"``

    The Main Frame AddOn Frame I am trying to hide to hide the whole addon is created in XML as: ``

    <Frame name="MyFirstFrame_Frame" enableMouse="true" movable="true">
        --various layers strings etc here Script for including my lua is also above
    </Frame>

    `` The Offending Lua is as such: `` SLASHCTA1 = '/cta'; CTAVISIBILITY = true;

    function MyFirstFrame_handler(msg, editbox)

    if CTA_VISIBILITY then
    MyFirstFrame_Frame:Hide();
    CTA_VISIBILITY = false;
    else if not CTA_VISIBLITY then
        MyFirstFrame_Frame:Show();
        CTA_VISIBLITY = true;
    end
end

    end SlashCmdList["CTA"] = MyFirstFrame_handler;``

    The Error posted first pops up when it hits MyFirstFrame_Frame:Hide(); Been stuck on this for a while, seems like this should be simple to show or hide a frame built in XML based on a slash command. Any help would be appreciated.
