Gui Not Tweening?

Problem: The Following script will not change the size of the bar(a frame) when value changes, I have checked while playing in studio and the Value DOES change. It is a number value

No output Errors

I debuged It and it stops printing at Val.Changed/Bar:Tween

Update: I have now found out that it does fire the function when the value changes but the gui does not tween, this script is in the frame I want to tween, yes I have tried to use script. Parent

Script

local Val = script.Parent.Parent:WaitForChild('MyThirst')
local Bar = script.Parent
local Size = .02 * Val.Value

Val.Changed:connect(function(NewValue)
Bar:TweenSize(UDim2.new(.02 * NewValue, 0,0.44, 0)) 
end)

I have also tried

local Val = script.Parent.Parent.MyThirst
local Bar = script.Parent
local Size = .02 * Val.Value

Val.Changed:connect(function(NewValue)
Bar:TweenSize(UDim2.new(Size, 0,0.44, 0)) 
end)

Also tried

local Val = script.Parent.Parent:WaitForChild('MyThirst')
local Bar = script.Parent
local Size = .02 * Val.Value

Val.Changed:connect(function(NewValue)
Bar:TweenSize(UDim2.new(.02 * NewValue, 0,0.44, 0),1) 
end)

From what I understand about Tweening, you need to provide an EasingStyle as well as a time and Direction. So the line of code that controls the TweenSize should look like this:

Bar:TweenSize(UDim2.new(.02 * NewValue, 0,0.44, 0), "Out", "Quad", 1)

I could be completely wrong though. If it doesnt work, sorry. Thats all I can think of.
