I have done what you said;
Round: isbreak="undefined"; breaknum="1" is the response.
http://mobile.hitmenpoker.com is the site, if you wish to see.
In reading the code, it looks like there is no definition for isbreak.
var theChipCount = parseInt(TDStatus.Vars["chipcount"]);
var thePlayersLeft = parseInt(TDStatus.Vars["playersleft"]);
var theAvgStack = thePlayersLeft == 0 ? 0 : Math.floor(theChipCount / thePlayersLeft);
var theRound = (TDStatus.Vars["isbreak"] == 1) ? "On Break (" + TDStatus.Vars["breaknum"] + ")" : TDStatus.Vars["roundnum"];
var theNewClock = TDStatus.getClockValue(TDStatus.Vars["secondsleft"]) + (TDStatus.Vars["clockpaused"] == 1 ? " (PAUSED)" : "");
TDStatus.setValue("clock", theNewClock);
TDStatus.setValue("round", 'isbreak="' + TDStatus.Vars["isbreak"] + '"; breaknum="' + TDStatus.Vars["breaknum"] + '"');
TDStatus.setValue("blinds", TDStatus.getChipsString(TDStatus.Vars["bigblind"]) + " / " +
TDStatus.getChipsString(TDStatus.Vars["smallblind"]));
TDStatus.setValue("ante", TDStatus.getChipsString(TDStatus.Vars["ante"]));
$("#ante").css({ display: TDStatus.HideZeroAnte ? "none" : "" });
$("#label_ante").css({ display: TDStatus.HideZeroAnte ? "none" : "" });
$("#space_ante").css({ display: TDStatus.HideZeroAnte ? "none" : "" });
TDStatus.setValue("players", thePlayersLeft + " / " + TDStatus.Vars["buyins"]);
TDStatus.setValue("averagestack", TDStatus.getChipsString(theAvgStack));
TDStatus.setValue("pot", TDStatus.getMoneyString(TDStatus.Vars["pot"]));
TDStatus.setValue("lastupdated", "" + new Date(parseInt(TDStatus.Vars["time"]) * 1000));
