Custom chat not working when I attempt to filter string value?

I made a custom chat that works perfectly when I don't try to add a filter. When I do, though, everytime I chat the custom chat display shows "Value". I never have done text filtering before so that's probably why. I looked at the wiki but I don't really get it... This is one of the local scripts for the custom chat:

chatbar.FocusLost:connect(function(EnterPressed)
	if EnterPressed and chatbar.Text ~= nil and chatbar.Text ~= " " then
		
		local message = chatbar.Text
		local plr = chatbar.Parent.Parent.Parent
		local chatstorage = game.Workspace:WaitForChild("ChatStorage")
		local plrmessage = Instance.new("StringValue", chatstorage)
		-- filter stuff starts here
		local sucess, message = pcall(function()
			local filteredtext = message:FilterStringAsync(message)

		
		plrmessage.Name = plr.Name..": "..filteredtext -- filter stuff ends here

		wait(0.1)
		chatbar.Text = "Press \"/\" to chat!"
		end)
	end
end)

Yeah, I'm clueless of how to filter this. Can someone help?

In line 13, you are setting the name instead of the value property of the string value. Change it to this:

plrmessage.Value = plr.Name..": "..filteredtext -- filter stuff ends here
