Value cannot be converted to a number, but it isnt a number?

I’m trying to save the values inside of a table using Datastore, but it keeps telling me value cannot be converted to a number

The table:

local ValuesTable = {
	Rebirth = Instance.new("NumberValue", Values);
	Coins = Instance.new("NumberValue", Values);
	Gems = Instance.new("NumberValue", Values);
	GemAdd = Instance.new("NumberValue");
	Keys = Instance.new("NumberValue", Values);
	Pity = Instance.new("NumberValue")
}

The script:

for i, v in pairs(ValuesTable) do
	v.Value = sessionData[player.UserId][v.Name]
end

It works when I do this though:

for i, v in pairs(ValuesTable) do
	v.Value = sessionData[player.UserId].JumpPower
end

But the issue with that is now everything is tied to the same savedata, but I need them each to be seperate, which is why I’m trying to change JumpPower to the name of the value, ex: Coins, Keys, etc…

And when I print v.Name, it comes out as their specified name, so I’m confused

I had these exact same issues. convert the values to numbers using the tonumber() function.

So here is a string:

print("5")

i would convert this into a number by using

print(tonumber("5") == 5) -- true

No problem, this should also help:
“Value cannot be converted to a number” warning in output - Help and Feedback / Scripting Support - Developer Forum | Roblox

Type ‘number?’ could not be converted into ‘number’ - Help and Feedback / Scripting Support - Developer Forum | Roblox
^^^ read this one especially, especially the comments.

I feel very silly rn, but I tried the thing and its not giving no more errors, but the data isn’t saving, I dont think I did it right but I’m not sure what to do

for i, v in pairs(ValuesTable) do
	local value = tostring(tonumber(v.Value))
	value = sessionData[player.UserId][v.Name]
end

Are there any errors in the output?

No errors but nothings saving, I’ll try showing a video

So I also tried it with the previous method:

for i, v in pairs(ValuesTable) do
		v.Value = sessionData[player.UserId].JumpPower
	end

	for i, v in pairs(ValuesTable) do
		v.Changed:Connect(function()
			sessionData[player.UserId].JumpPower = v.Value
		end)
	end

and it saves the values, but it saves them all at the same value since theyre saving to “JumpPower”

#11 
	for _, v in pairs(ValuesTable) do
		local name = tostring(v)
		print(name)
		v.Value = sessionData[player.UserId][name]
	end
	
	for _, v in pairs(ValuesTable) do
		v.Changed:Connect(function()
			local name = tostring(v)
			print(name)
			sessionData[player.UserId][name] = v.Value
		end)
	end

This ended up working, even though its giving me the same error for some of them, for some reason, it still saves normally
