How would i run this function when a string is changed?

Hi, the one suggestion I can think of is a StringValue object and then using the .Changed Event as you can see here StringValue which both shows what a string value is and explaining how .Changed works at the very bottom

local table = {
	"yes",
	"no",
	"lol"
}

local ValueChosen = Instance.new('StringValue')
ValueChosen.Value = 'hi'
ValueChosen.Changed:Connect(hi) when changed is fired for Value objects it fires what the value is changed to


function hi(newvalue) --newvalue in case the value chosen has an actual effect on what you want the code to do 
	print('hi')
end

--This will obviously work but i want to run the 'hi' function only when the 'valueChosen' is changed and run it again when 'valueChosen' is changed again
--I'm not sure if it's possible which is why I'm asking for help here
--hope my changes answer the questions you have here^

I hope this helps feel free to comment if you have any further questions
