Undefined var - no idea why!

1

hey guys, I am having problems working out the difference between two numbers… here is the code that I am using:


var rawDifference:Number;
var minuteDifference:Number;
function calculateMinuteDifference() 
   {
   rawDifference = currentMinute - recentMinute2;
      if (rawDifference < 0)
      {
         minuteDifference = 60 + rawDifference;
      }
      else if (rawDifference > 0)
      {
         minuteDifference = rawDifference;
      }
}

and the output i get is:

   //The Raw Difference is: undefined
   //The Difference in Minutes: undefined

does anybody have any idea why this might be happening?
thanks in advance :slight_smile:
