Freezing error with certain code... Help?

I am trying to make a HUD that changes depending on how many conditions are met, but each time I try to make it change in Studio's Play Mode (by editing the value's String in the Explorer), the game freezes forever...

Code :

-- All variables are correctly defined above in the script. If you need them, comment the question with the request, and I will edit this code block.

while true do
	if main.Value == "" and sub.Value == "" then
		print("main & sub are empty")
		pBG.Position, hBG.Position = pos[1], pos[2]
		mtBG.Visible, mA.Visible, mBG.Visible = false, false, false
		stBG.Visible, sA.Visible, sBG.Visible = false, false, false
		wait(1)
	elseif not main.Value == "" and sub.Value == "" then
		print("only sub is empty")
		pBG.Position, hBG.Position = pos[4], pos[5]
		mtBG.Position, mA.Position, mBG.Position = pos[1], pos[2], pos[3]
		mtBG.Visible, mA.Visible, mBG.Visible = true, true, true
		stBG.Visible, sA.Visible, sBG.Visible = false, false, false
		wait(1)
	elseif not main.Value == "" and not sub.Value == "" then
		print("nothing is empty")
		pBG.Position, hBG.Position = pos[7], pos[8]
		mtBG.Position, mA.Position, mBG.Position = pos[4], pos[5], pos[6]
		stBG.Position, sA.Position, sBG.Position = pos[1], pos[2], pos[3]
		mtBG.Visible, mA.Visible, mBG.Visible = true, true, true
		stBG.Visible, sA.Visible, sBG.Visible = true, true, true
		wait(1)
	end
end

The Studio's Output window does not give any error, because the game freezes as soon as another value check is ran.

Any help will be appreciated!

Pyrondon is correct. The only reason a while loop would freeze, is if it constantly loops without waiting. After your last "elseif", put

else wait() -- or wait(1)

As long as the script has a 'time to breathe', it won't freeze.
