Calculate percentage Javascript

Question

I have a question about javascript logic what I use to get percent of two inputs from my text fields  Here is my code       var pPos       pointspossible   val        var pEarned       pointsgiven   val         var perc     pEarned pPos    100  toFixed 3           pointsperc   val perc     For some reason if my inputs are 600 and 200  my result suppose to be  33 333 but I m getting 3 333  If I hard code my values this works fine  If anyone can help I appreciate that  Thanks in advance
