hey, i added a PM system into my player menu but the problem is that players can send empty messages so im trying to cancel that but dunno why dosnt works, here is my code.

addEvent ("sendMsg", true)
addEventHandler ("sendMsg", getRootElement(),
function(msg,client)
local givenplayer = getPlayerFromName ( client )	
if( givenplayer ) then
if msg == nil then
outputChatBox ( "* PM from " .. getPlayerName(source) .. ": " ..msg.. ".", givenplayer, 243, 151, 12 )
else
outputChatBox ("Error: You cant send empty messages.", source, 255, 0, 0, false)
end	
end
end)

Thanks in advance.

If msg is always string then it will never be nil. You can check if string is empty by checking its length (with #) or "".

if msg == "" then
-- message is empty...
end
-- OR
if #msg == 0 then
-- message is empty...
end

post whole code maybe?

or try

if msg==nil or msg=='' or msg==false then

Solid, it's irrelevant here to your question, but read your code more carefully, specifically line 6 and think about how it would work.
