Why is this not saving the text in a datastore?

I have a server script:

local ds = game:GetService("DataStoreService")
local record = ds:GetDataStore("Records")
game.ReplicatedStorage.save.OnServerEvent:Connect(function(sender, target, message)
	print("fired, "..sender.name.." to "..target.name.." message is "..message)
	local frame = game.StarterGui.Record.Frame
	local success, errormessage = pcall(function()
	record:SetAsync(target.userId, message)
	end)
	if success then
			frame.save.Text = "Succsesfully sent!"
	else
		print("that aint it chief")
		warn("here is the error "..errormessage)
	end
end)

Lua is Case Sensitive, so you need to have the proper naming of your properties.

Change Line 7 to

record:SetAsync(target.UserId, message)

and change Line 5 to

local frame = target.PlayerGui.Record.Frame
