If you use this:

pawn Код:

if(IsValidSkin(id))
    {
    SendClientMessage(playerid, COLOR_GRAD2,"You cannot buy this clothes");
    return 1;
    }

It will send you that client message if the skin is valid. Use this, and it will work:

pawn Код:

if(!IsValidSkin(id))
    {
    SendClientMessage(playerid, COLOR_GRAD2,"You cannot buy this clothes");
    return 1;
    }
