Solution

You can place a NumberValue in ReplicatedStorage, which can be accessed by both server scripts and local scripts. If you want it to be accessible only by server scripts, use ServerStorage instead.

Demonstration

As a demonstration, place a NumberValue in ReplicatedStorage as shown:

Create two server scripts, the first named "Primary Script", and the second named "Other Script":

game.ReplicatedStorage.BarierNumber.Value = 123
print("Primary Script:", game.ReplicatedStorage.BarierNumber.Value)

print("Other Script:", game.ReplicatedStorage.BarierNumber.Value)

Then, create a local script called "Local Script":

print("Local Script:", game.ReplicatedStorage.BarierNumber.Value)

Then, run the game and notice that all scripts retrieve the correct value:
