public LoginUser(query[],playerid,AutoLogin,connectionHandle) // line 270

{ // is line 330

it means you have it somewhere as

pawn Код:

new string[SIZE];

Twice,it could be defined as a global, or a local variable. Just change it where its needed.

don't use generic names like that for variables. You end up polluting the namespace.

What's more, using locals reduces the number of bugs caused by functions accessing the same variables and "pollutes" the global namespace less, making naming collisions less likely. If you really want to statically allocate all your arrays, use static locals rather than full globals.

So I should use local variable for this? Right?

Re: Warning 219 Help - PrinceKumar - 21.07.2013

it means you have already use new string so don't use it again find for new string in your script if it is under include but before gamemodeinit or fiterscriptinit so delete it
edit: and see line before 270 which have new string , i think there will be a mistake

Re: Warning 219 Help - Scenario - 21.07.2013

"string" is probably defined in one of your includes.
