H1=script.Parent.H1
Btw, this is in a local script, in StarterPack. There is a bool value in StarterPack named "H1". And this is what I get:
"01:54:52.716 - H1 is not a valid member of Backpack"
If you have any advice, I appreciate it.
When it comes to the Character, PlayerGui, and Backpack, not everything loads at the same time.
The problem is likely that the LocalScript is placed in the backpack before the H1 BoolValue.
Use
H1 = script.Parent:WaitForChild("H1")
to get the object, but wait for it to appear if it's not yet there.
