Can not get this code to work!

I believe this to be the correct way, im sure its a simple syntax mistake but I can not see it! please help!

var temperatures = [100,90,99,80,70,65,30,10];

for (var i = 0; i < temperatures.length; 1++;) {
<!DOCTYPE html>
  <meta charset="utf-8">

Found another error - sorry for the delay on this. Can't have a semi-colon following the increment step.

// change this
for (var i = 0; i < temperatures.length; 1++;)

// to this
for (var i = 0; i < temperatures.length; i++)

Tested and works.

i tried it like 5 times and it still was not working but before i threw my computer out the window i decided to close the browser and reopen it and it worked... so it must have been a bug on top of my original syntax errors! alas it is working now! thank you very much!

Hi Eric,

Your loop is trying to increment the value of 1 instead of the value of i.

yeah that must have been a typo, I did change the 1 to "i ++" and i also tried "i +=" like the video and still getting parse error.

There can't be a space when using i++. Also, you can use i += but there must be a value for it to increment by. So, i += 1 would work.
