My hp/mana/level/gold ect lost connection to the script?

So this might be a pretty big request, but i was creating with a gui and during testing i noticed my hp/mana/gold/and character speed/level all were broken, as if they all had no script attached to them.

They are all under StarterGui.HUD.Base

im not sure if something happened in the script, cant see that it would i didnt touch anything around the time it broke but heres the script they should all be attached to.

its a pretty big one, and im not sure if something happened where it lost connection to Base

If there is nothing wrong there is there something else that could have happened to cause this? all of the guis are stuff under Baseand all have their correct name as before they were broken.

any and all help is appreciated :) thanks for looking
