Noob Help! Moving Casting bar

[ErMeR]

I'm trying to get my feet wet with LUA and scripting in WoW but I'm having a little bit of trouble with my latest project which is to make a mod that lets me move the casting bar with the mouse and lock it and unlock it with two simple commands.

Here is what I have so far in my .lua:

function MovableCastingBar_Unlock()

	CastingBarFrame:Show();
	CastingBarFrame:StartMoving();
	
end

function MovableCastingBar_Lock()

	CastingBarFrame:Hide();
	CastingBarFrame:StopMovingOrSizing();
	
end

CastingBarFrame:SetMovable();
CastingBarFrame:EnableMouse();

SLASH_CASTINGBARUNLOCK1 = "/mcbu";
SLASH_CASTINGBARUNLOCK2 = "/mcbunlock";
SlashCmdList["CASTINGBARUNLOCK"] = MovableCastingBar_Unlock;

SLASH_CASTINGBARLOCK1 = "/mcbl";
SLASH_CASTINGBARLOCK2 = "mcblock";
SlashCmdList["CASTINGBARLOCK"] = MovableCastingBar_Lock;

Whenever I unlock the frame it shows up like it is supposed to, but I cannot move it nor can I touch any of my action bar buttons until I lock it again. When I lock the frame it has not moved at all

Any help would be much appreciated, I am just beginning and having troubles
