html code for Google Maps not working properly

I'm just learning how to use google maps in my code, but I'm having trouble getting the actual map to appear on the browser screen. All that appears are the two drop down boxes that allows the user to choose their starting and ending locations. Any help would be greatly appreciated!

Directions.html

This file is what sets the size of the map div in the example you copied from:

/maps/documentation/javascript/examples/default.css

Which contains:

html, body {
  height: 100%;
  margin: 0;
  padding: 0;
}

#map-canvas, #map_canvas {
  height: 100%;
}

@media print {
  html, body {
    height: auto;
  }

  #map_canvas {
    height: 650px;
  }
}

It doesn't exist on your server, either copy it there, copy the content into your HTML file (inside <style> tags), or link to the file on Google's servers (not recommended, as it might change, but it will make the map show up).
