    why for this question for so long time and no any answer?

  • Rather than return NaN return my.value which will just returns it's current value.

  • Thanks,Joels.
    In meta if I have 15 value,(I have set cron in the meta),from the 15th value start ,when 15th.value>2,then need to continute 14th value. if 15th<2, then 14th value to compare with 2.if 14th.value>2 ,then end . if 14th.value<2, then 13th will compare with 2. if every value all 15 is less than 2.then will undisplay vlaue. this is my script. Is it right? Need your modify.


    var n=1
    switch (n)
    case 1:
    if (p15.value>2.0)
    { return p15.value;}

    case 2:
    if (p15.lastValue(1)>2.0)
    return p1.lastValue(1);
    case 3:
    if (p15.lastValue(2)>2.0)
    return p1.lastValue(2);
    case 4:
    if (p15.lastValue(3)>2.0)
    return p1.lastValue(3);
    if if (p15.lastValue(15)>2.0)
    return p1.lastValue(3);
    return (NaN);
