I need help finding a fix for the (probobly) simple mistake?[SOLVED]

THIS script is for a passcode Gui that requires you to put the games passcode into the gui to prevent wandering people from looking at my game.

Everything works except the "tries" part of it. What the "tries" part is, is that when a player inputs the wrong code, one is added to the "tries," and when they input 5 incorrect codes, the frame will get deleted, and left with a black screen (the frame that is getting deleted is inside another black frame that covers the whole screen)

tries = 0

function onButton1Down()
local passwordvalue = script.Parent.Parent.Password.Value
if script.Parent.Parent.TextBox.Text == passwordvalue or script.Parent.Parent.TextBox.Text == passwordvalue:lower() or script.Parent.Parent.TextBox.Text == passwordvalue:upper() then
script.Parent.Parent.Right.Visible = true
script.Parent.Parent.Status.Visible = false
wait(1)
script.Parent.Parent.Parent.Visible = false
else script.Parent.Parent.Status.Text = "Wrong Passcode"
	tries =  +1             --this is where im having trouble
	
	script.Parent.Parent.Status.Visible = true
	wait(0.1)
	script.Parent.Parent.Status.Visible = false
	wait(0.1)
	script.Parent.Parent.Status.Visible = true
	wait(0.1)
	script.Parent.Parent.Status.Visible = false
	wait(0.1)
	script.Parent.Parent.Status.Visible = true
 if tries == 5 then
	script.Parent.Parent.Status.Text = "Incorrect too many times!"
	wait(1)
	script.Parent.Parent.Status.Text = "You are locked out!"
	wait(1)
	script.Parent.Parent.Status.Text = "Incorrect to many times!"
	wait(1)
	script.Parent.Parent.Status.Text = "You are locked out!"
	wait(1)
	script.Parent.Parent:Destroy()
end
	
end
end

script.Parent.MouseButton1Down:connect(onButton1Down)

Sorry if this is too confusing...
