Try this:
PHP код:
CMD:changegatepass(playerid, params[])
{
    new string[128];
    if(isnull(params)) return SendClientMessageEx(playerid, COLOR_WHITE, "USAGE: /changegatepass [pass]");

    if(strlen(params) > 24)
    {
        SendClientMessageEx(playerid, COLOR_GRAD2, " Must be 24 characters or less! ");
        return 1;
    }
    new ownsgate;
    for(new i = 0; i < sizeof(GateInfo); i++)
    {
    if(PlayerInfo[playerid][pPhousekey] == GateInfo[i][gHID] && PlayerInfo[playerid][pPhousekey2] == GateInfo[i][gHID])
        {
            ownsgate = 1;
            format(string, sizeof(string), "Gate Password for gate %d changed to %s", i, params);
            format(GateInfo[i][gPassword], 24, "%s", params);
            SendClientMessageEx(playerid, COLOR_GRAD2, string);
            SaveGates();
        }
    }
    if(!ownsgate) SendClientMessageEx(playerid, COLOR_WHITE, "* You don't own a gate");
    return 1;

}

First of all, don't use a semicolon in an "if".
Second, you end the if, and then try continuing it with &&, you've opened 2 parenthesises as marked here with red and darkred:
Quote:

if((PlayerInfo[playerid][pPhousekey] == GateInfo[i][gHID])) && (PlayerInfo[playerid][pPhousekey2] == GateInfo[i][gHID]);
And then you close them again, so essentially the if is done, but then you try using && PlayerInfo, although you already ended the if.
It's like braces, you're trying to do something like this:
pawn Код:
public OnGameModeInit()
{
    print("Gamemode started.");
}

print("Welcome to your new gamemode.");
You cannot do this, as you already ended the OnGameModeInit function, you gotta do it like this:

if((PlayerInfo[playerid][pPhousekey] == GateInfo[i][gHID]) && (PlayerInfo[playerid][pPhousekey2] == GateInfo[i][gHID]))
