Well, you need to learn about elseif. Currently if the invitedFor isn't equal 7, you'll get error

BTW: Your code can be a little shorter (which also includes the fix)

pawn Код:

CMD:invite(playerid, params[])
{
    new player;
    if(sscanf(params, "u", player)) return SendClientMessage(playerid, COLOR_YELLOW, "Usage: /invite [playerid / name]");
    if(player != INVALID_PLAYER_ID)
    {
        if(PlayerInfo[playerid][pLeader] == 1 && 1 <= PlayerInfo[playerid][pTeam] <= 7)
        {
            new string[128];
            new stringtarget[128];
            new pName[MAX_PLAYER_NAME], aName[MAX_PLAYER_NAME];
            GetPlayerName(playerid, aName, MAX_PLAYER_NAME);
            GetPlayerName(player, pName, MAX_PLAYER_NAME);
            invitedFor[player] = PlayerInfo[playerid][pTeam];
            format(string, sizeof(string), "You have invited %s to join %s", pName, FactionStatus(playerid));
            format(stringtarget, sizeof(stringtarget), "You have been invited to join %s. Type "COL_RED"/acceptinvite"COL_WHITE" to join!", FactionStatus(playerid));

            SendClientMessage(playerid, COLOR_LIGHTBLUE, stringtarget);
        }
