How do i have a string value in data saves show on a gui?

In the game.Players.Name.Data.DevilFruit The devilfruit is a string value and i want it to show up on a text gui what script do i use to make it show up? I already have 1 but it only works on integers not string values, the script is.

while true do
script.Parent.Text = "DevilFruit" .. math.floor(script.Parent.Parent.Parent.Parent.Parent.Data.DevilFruit.Value)
wait(1)
end
