TextBox to StringValue.Value not working?

Hello, I've gotten back into coding after a long break (3ish years) so i've forgotten a lot, why isn't this script working. The point is to make a stringvalue which is the child of the textbox the same value as the text box .text. but when run the game the string values's value is nothing no matter what i do

function click ()
local F = script.Parent
local FC = F.Text
script.Parent.TextV.Value = FC
print(script.Parent.TextV.Value)
end
script.Parent.Changed:Connect(click)
