ReplicatedStorage not working?

for some reason this doesn't work

regen = game.ReplicatedStorage:GetChildren()

h = Instance.new("Hint",game.Workspace)
while true do
for i = 30, 0, -1 do
    wait(1)
    h.Text = "Time Until Snow Falls:".." "..i
    if i == 0 then
        h.Text = "Oh no! Snow covered the ground...again"
        for i, v in pairs(regen)do
            if v.Name == "Snow" then
            v.Parent = game.Workspace
                end
            end
        end
    end
end
