Having errors with "Sum All Numbers in a Range" exercise

i have been trying to solve the exercise on sum all numbers in a range and i am facing some issues.
This is my code so far. it returns the right value but does not validate the exercise.

I like some help on how to solve this problem

var sumArr = [];
function sumAll(arr) {
   var maxVal = Math.max(arr[0], arr[1]);
   var minVal = Math.min(arr[0], arr[1]);
  while(minVal <= maxVal){
   var sumTotal = sumArr.reduce(function(sum, value){
     return (sum + value);
   }, 0);
  return (sumTotal);

sumAll([10, 5]);

Link to the challenge:

Try moving the

var sumArr = [];

inside the function. Declaring it globally will not work with the FCC tests, because it would not get reset to a blank array as the tests are ran consecutively.

Thank you. it worked
