Script dosent work when put into StarterPlayer?

So basically, this script changes the text label on a surface GUI, and it works fine in workspace, but if the part is put into Starter Player, (Where its supposed to go) it doesn't work. any help?

Label=script.Parent.Label

Interval=5 -- Time Between Change

  

while true do

Label.Text=" " -- The 1st Text Shown

wait(Interval)

Label.Text="Hey dude" -- The 2nd Text Shown

wait(Interval)

Label.Text="Not sure if you will see this" -- The 3rd Text Shown

wait(Interval)

Label.Text="Youve been missing for some time." -- The 4th Text Shown

wait(Interval)

Label.Text="..." -- The 4th Text Shown

wait(Interval)

Label.Text="Im not sure if you know about the outbreak. be safe." -- The 4th Text Shown

wait(Interval)
