Help with this code.

[Feche1320]

I don't want to people abuse commands, so I did this:

if(getTickCount()-g_PlayerTick[source] < 20000) then 
        outputChatBox("Please wait 20 seconds between commands.", source, 255, 0, 0) 
        return 
    else 
        --more code 
       g_PlayerTick[source] = getTickCount() 
    end 

But the first line gives me this error:

 attempt to perform arithmetic on field '?' 

Thanks

try:

  
if(g_PlayerTick[source] and getTickCount()-g_PlayerTick[source] < 20000) then 
  

that's assuming the first time a player uses a command their tick value hasn't been set.
