Help me with this challenge

I don't know why It isn't working. It says Task 1 is no longer passing.

script.js 
var coordinates = [
  [123, 456], 
  [834, 678],
  [654, 956],
  [237, 049],
];
index.html

It is a syntax error. On your last array element, there shouldn't be a comma, as that would make the compiler assume that another element will come after it, which is not the case here, so remove that last comma.

EDIT: It is because you have the last comma there, and your final number 049 is not a valid integer, you need to enter 49.

I thought the same, but I remove the last comma and it doesn't work.
