LUA Errors - DarkRP

I am getting some LUA errors in my server that i am not to sure how to fix. These errors are obviously from my latest server add-on which was DarkRP Chat Tags, but i want to know what you guys make of these errors.

[ERROR] gamemodes/darkrp/gamemode/cl_init.lua:822: attempt to call global ‘ValidEntity’ (a nil value)

  1. Function - gamemodes/darkrp/gamemode/cl_init.lua:822
  2. unknown - lua/includes/modules/usermessage.lua:87

Line 822 = if ValidEntity(ply) then

Line 87 = include(“client/helpvgui.lua”)

I’m not too great with LUA so if this is an obvious fix or is just a stupid question than “my bad” lol

Change ValidEntity to IsValid,
So it will be:
[lua]if IsValid(ply) then[/lua]
It will solve it all.

Thanks it worked!
