so basically I want to make a surfacegui which displays a random chosen word from a list. how do I do that?

local textLabel = script.Parent.TextLabel

local strings = {"1BTC", "2BTC", "3BTC"}
local random_number = math.random({1, #strings})
local picked_string = strings[random_number]

print(picked_string)

I tried this but doesn't work
