[Help] expression has no effect - Warning. - Miikkel - 06.07.2010

I have this little code for my Roleplay Gamemode.
But it comes up with warnings saying:

Quote:

C:\Users\Mikkel\Desktop\SA-MP Server\gamemodes\TeRP.pwn(457) : warning 215: expression has no effect
C:\Users\Mikkel\Desktop\SA-MP Server\gamemodes\TeRP.pwn(462) : warning 215: expression has no effect
Pawn compiler 3.2.3664 Copyright © 1997-2006, ITB CompuPhase

2 Warnings.

Code:

pawn Код:

if(dialogid == 2) //Sex Dialog Box
    {
        if(response)
        {
            if(listitem == 0)
            {
                pInfo[playerid][pSex] == 1; //Male - Line 457
                SetPlayerSkin(playerid, 299);
            }
            else if(listitem == 1)
            {
                pInfo[playerid][pSex] == 2; //Female - Line 462
                SetPlayerSkin(playerid, 298);
            }
        }
    }
    return 1;

I want it to store the Sex ID in the pSex.

pawn Код:

pInfo[playerid][pSex] == 1;
pInfo[playerid][pSex] == 2;

== means "is equal to". It's used in statements like these:

pawn Код:

if(pInfo[playerid][pSex] == 2)
{
   doSomething();
}

You're supposed to use:

pawn Код:

pInfo[playerid][pSex] = 1;
pInfo[playerid][pSex] = 2;

That way pInfo[playerid][pSex] is assigned to either 1 or 2.

I think what it is saying is that those two words - new sf; and new sf2; are not being used in the script.
I think you can just delete them.

See if that helps, if it causes errors place them back.
Also its just a warning, you are still aloud to use your script.
