Note GUI Open script opens once in actual game, perfectly fine in studio?

This script works fine in studio but when I test it out, it only opens once and when you try to open it again, it doesn't work. (SCRIPT IS A NORMAL SCRIPT INSIDE OF A PART WITH CLICK DETECTOR)

text_wrapped = true
--If true, sentences will auto-move to the next line.

--Double square brackets lets tabs and new lines work easily.

[[
I an't suppose to see anything that goes in between this gate and the walls of that old aslyum. However, some word did spill out of the creaks of the walls stating that what they do in there is illegal. Not my problem. I am just the gate keeper.
