jQuery - Problems checking text for acquired "selected" drop down option.

I have managed to grab the text of a selected option from a drop down, but when I assign that value to a variable and run it through a conditional statement it doesn't work.  I run a "alert ( variable )" to see what value was assigned to the variable and see that it does obtain one of the conditions "true".  But an odd thing is that the "alert" window puts the text all the way to the right (SEE ATTACHED FILE) of a screen shot of what I mean.

Details:
- Drop down with: class="choice"
- Drop down contains to options: "Someone Else" and "Me" as your two choices
- By default the drop down has "Me" selected. I need to see when the drop down changes (.change(function()) if "Someone Else" was selected.

NOTE: I have an alert ( ) there to return what is in the variable so I can see myself and it always returns blank.

Here is my attempted code:

<script type="text/javascript">
jQuery.noConflict();
   jQuery(document).ready(function(){
      jQuery(".optional-field").hide();
      jQuery(".warning").hide();
          
  jQuery(".choice").change(function() {
   var choice = jQuery(".choice option:selected").text();
   alert (choice);
 
      if (choice == 'Me') {
         jQuery(".optional-field").hide();
         jQuery(".warning").hide('slow');
      } else if (choice == 'Someone Else') {
         jQuery(".optional-field").show('slow');
         jQuery(".warning").show('slow');
      }
   });
});
 
</script>
