Can't change integer in ReplicatedStorage, help?

I am attempting to change an integer value in my replicated storage but to no avail.

using the following code:

local Gain = game:GetService("ReplicatedStorage"):WaitForChild(ClientModuleStorage"):WaitForChild(ClientDataStorage_Module").Income_Item["Canoe"].MuscleGain;

Gain.Value = Gain.Value * 1000;

end);

My ClientDataStorage_Module looks like this:

local v1 = {
	BadgeId = {
		Stickman = 2124484013, 
		Beast = 2124484014
	}
};
v1.Income_Item = { {
		Name = "Pencil", 
		MuscleGain = 1, 
		Price = 0, 
		MuscleBounce = 1
	}, {
		Name = "Log", 
		MuscleGain = 370, 
		Price = 75500, 
		MuscleBounce = 1
	}, {
		Name = "Canoe", 
		MuscleGain = 555, 
		Price = 111000, 
		MuscleBounce = 1
	} };

I see that you're inquiring via module script, in this case please use the 'require' function. Please replace

local Gain = game:GetService("ReplicatedStorage"):WaitForChild(ClientModuleStorage"):WaitForChild(ClientDataStorage_Module").Income_Item["Canoe"].MuscleGain;

To:

local Gain = require(game:GetService("ReplicatedStorage"):WaitForChild(ClientModuleStorage"):WaitForChild(ClientDataStorage_Module").Income_Item[3].MuscleGain)

Remove the .Value previous to 'Gain', since a table key isn't a value:

Gain = Gain * 1000

Also in ClientDataStorage_Module, if there's none, please add in the bottom of the script:

return v1

In case if you have removed it you have to add it else it won't work.
