pawn Code:

CMD:Glasses(playerid, params[])
{
    new glasses = strval(params);
    new skin = GetPlayerSkin(playerid);
    if(!glasses || glasses > 30) return SendClientMessage(playerid, 0xFFFFFFAA, "(Error) Syntax: /glasses [1 - 30]");
    new glasseid =  CommonRed + (glasses - 1);
    SetPlayerHoldingObject(playerid, glasseid, 2, SkinOffSet[skin][0], SkinOffSet[skin][1], SkinOffSet[skin][2], SkinOffSet[skin][3], SkinOffSet[skin][4], SkinOffSet[skin][5]);
    TextDrawShowForPlayer(playerid, MsgBox);
    SetTimerEx("Hide", 3500, false, "d", playerid);
    return 1;
}

You don't need to use strtok for one param.
