can anyone spot the issue with my $.getJSON() method on line 8?

Bummer: You didn't correctly call the $.getJSON() method. To use it, pass it three arguments: the URL, the data you want to send to the server, and the callback function.

weather.js 
$(document).ready(function() {

  var weatherAPI = "http://api.openweathermap.org/data/2.5/weather";
  var data = {
    q : "Portland,OR",
    units : "metric"
  };
  $.getJSON(weatherAPI, data, function (weatherReport) {
    $('#temperature').text(weatherReport.main.temp);
  });
});
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>What's the Weather Like?</title>
  <script src="jquery.js"></script>
  <script src="weather.js"></script>
</head>
<body>
  <div id="main">
    <h1>Current temperature: <span id="temperature"></span>&deg;</h1>
  </div>
</body>
</html>

You're code is correct, but to complete the challenge pass the function that is already present to getJSON (i.e. do not use an anonymous function).

hey Clayton, thanks for the response. Unfortunately I have tried that approach as well but still got an error message.

strange this passes for me

$(document).ready(function() {

  var weatherAPI = 'http://api.openweathermap.org/data/2.5/weather';
  var data = {
    q : "Portland,OR",
    units : "metric"
  };
  function showWeather(weatherReport) {
    $('#temperature').text(weatherReport.main.temp);
  }

  $.getJSON(weatherAPI, data, showWeather);

});
