Why does this text label change with the first value, but not change any other time?

I'm trying to make a GUI that changes along with a value, but it only changes the first time.

local text = script.Parent
local val = script.Parent.cash.Value

text.Text = tostring(val) 

val.Changed:Connect(function() 
    text.Text = tostring(val)
end) 

Thanks if you can help.

DO NOT USE A LOOP (this is to the previous answer)

The reason it doesn't work is that the variable val is an actual number. You can't do .Changed on a number. Here is a complete fix:

local text = script.Parent
local val = script.Parent.cash

text.Text = val.Value

val.Changed:Connect(function() 
    text.Text = val.Value
end) 

When using Variables to define a value, do not put .Value at the end. This is because you want a updating value. The current value will always stay the same if you use the Variable again.

Hopefully, this helped you solve your problem!
