I dont know what you are using and that "ShowPlayerDialog" at the end is just ... wrong. Here's a small fix

pawn Код:

if(dialogid == DIALOG_ARMY)
{
if(!response)
{
    SendClientMessageEx(playerid, COLOR_WHITE, "SERVER: You have been kicked out of the server because you failed to respond.");
    Kick(playerid);
}
switch(listitem)
{
    case 0:
    {
        SetPlayerTeam(playerid,1);
        SetPlayerSkin(playerid,287);
    }
    case 1:
    {
     SetPlayerTeam(playerid,2);
     SetPlayerSkin(playerid,285);
    }
}

If you need more help, provided a little bit more code.
