    var direction = 'down';      var mins = 30;      var secs = mins * 60;        function colorchange(minutes, seconds) {        var minutes = document.getelementbyid('minutes');        var seconds = document.getelementbyid('seconds');        var colon = document.getelementbyid('divide');          var color;        if (direction == 'up') {          color = 'black';        } else if (secs <= 30) {          color = 'red';        } else if (secs <= 59) {          color = 'orange';        }        minutes.style.color = seconds.style.color = colon.style.color = color      }        function getminutes() {        // minutes seconds divided 60, rounded down        mins = math.floor(secs / 60);        return ("0" + mins).substr(-2);      }        function getseconds() {        // take mins remaining (as seconds) away total seconds remaining        return ("0" + (secs - math.round(mins * 60))).substr(-2);      }        function countdown() {        setinterval(function() {          var minutes = document.getelementbyid('minutes');          var seconds = document.getelementbyid('seconds');            minutes.value = getminutes();          seconds.value = getseconds();          colorchange(minutes, seconds);            if (direction == 'down') {            secs--;            if (secs <= 0) {              direction = 'up';            }          } else if (direction == 'up') {            secs++;          }        }, 1000);      }          countdown();
