I clear first three tasks and than as soon as I answer question 4 I get stuck as it says "Task 1 is no longer passing".

I have'nt changed task 1 and my answer to task 4 is also correct.

      The JavaScript Math object has the following
      constant (among others):
      Math.PI
          Approximately 3.14159. Pi (π) is used
          to determine the circumference of a circle
          given its diameter by multiplying the diameter
          by π. Geometery refresher: the circumference
          of a circle is the distance around the outside
          edge. The diameter is the width of the circle.

      The JavaScript Math object also has the following
      methods (among others):
      Math.random()
          Returns a random number between 0 and 1
      Math.max(a, b, ...)
          Returns the largest value of the passed
          arguments
      Math.floor(a)
          Returns the value of a number rounded down to
          the nearest integer

Change ageIfLiveToYear2100 to ageIfILiveToYear2100 You were missing an "I" originally (try to copy and paste long variable names to avoid misspelling it.

Not sure why it threw out that error for stage one, but this made it pass the test. For reference the following code should pass all stages:

  var circumference = diameter*Math.PI;

  var chance = Math.random()*20;

  var maxWidth = Math.max(a,b,c);

  var age = Math.floor(ageIfILiveToYear2100);
