Sum All Odd Fibonacci Numbers becomes unresponsive

Tell us what’s happening:

Hi. I was working on the Sum All Odd Fibonacci Numbers challenge. I deleted a portion of the code, and now the tab becomes unresponsive everytime I try to visit the page. Does freecodecamp automatically execute the code on opening the browser? Any help on resolving this issue would be appreciated.

Your code so far
function sumFibs(num) {
var sum = 0;
var a=0;
var b=1;
var hold;
for (var i=1;i<num;i)
if (sum%2==0) {
