# Sum of all numbers in the range

Tell us what’s happening:
why is it logging 0 for everything i try ,even if i use push into an empty array its returning

``````
function sumAll(arr) {
let temp=0;
let max = Math.max(arr[0],arr[1])
let min= Math.min(arr[0],arr[1]);
for(var i=max;i<=min;i--){
temp += i
}
return temp
}
console.log(sumAll([1, 4]));

``````

Challenge: Sum All Numbers in a Range

``````for(var i=max;i<=min;i--){
``````

If you use that line:
|0|1|
|1|4|
is the outcome resulting eventually in an outcome of 0 in your code is that what you want?

that line is same as
for(i=4;i<=1;i–)

i dint get you what you are trying to say

It should be:

``````for(var i=max;i>=min;i--){
temp += i
}
``````

because i is max therefore you test if i >= min still not i <= min.
