Check if element exists causing script error in browser

I'm trying to attach the Qtip plugin to elements only if the elements containing certain text exists on the page. For some reason I keep getting a script error saying "AddTooltips() is not a function." on a page where the elements do not exist. Something isn't quite working with my if statement.

$(document).ready(function() {

 function AddTooltips() {
  var infoIcon = '<img class="actionItem catInfo" style="margin-left:4px" src="/images/00_Core/info.gif"/>';
  var $Age = $("div.question h3:contains('Age')");
  var $Gender = $("div.question h3:contains('Gender')");
  var $Questions = $("div.question h3:contains('Age'), div.question h3:contains('Gender')");
  $Questions.append(infoIcon);
  $.fn.qtip.styles.speStyle = { // Last part is the name of the style
   width: 400,
   border: {
    width: 2,
    radius: 6
   },
   name: 'light' // Inherit the rest of the attributes from the preset dark style
  };
  $Age.children("img.catInfo").qtip({content: 'Some Copy.', style: 'speStyle'
  });
  $Gender.children("img.catInfo").qtip({content: 'Some Different Copy.', style: 'speStyle'
  });
 }


 if ( $("div.que开发者_Go百科stion h3:contains('Age')").length > 0 || $("div.question h3:contains('Gender')").length > 0 ) {  
  AddTooltips();
 }
});

put AddTooltips() outside the dom ready event like so:

function AddTooltips() {
    var infoIcon = '<img class="actionItem catInfo" style="margin-left:4px" src="/images/00_Core/info.gif"/>',
        $Age = $("div.question h3:contains('Age')"),
        $Gender = $("div.question h3:contains('Gender')"),
        $Questions = $("div.question h3:contains('Age'), div.question h3:contains('Gender')");

    $Questions.append(infoIcon);
    $.fn.qtip.styles.speStyle = { // Last part is the name of the style
        width: 400,
        border: {
            width: 2,
            radius: 6
        },
        name: 'light' // Inherit the rest of the attributes from the preset dark style
    };
    $Age.children("img.catInfo").qtip({content: 'Some Copy.', style: 'speStyle'});
    $Gender.children("img.catInfo").qtip({content: 'Some Different Copy.', style: 'speStyle'});
}

$(function() {
    if ($("div.question h3:contains('Age'), div.question h3:contains('Gender')").length) {  
        AddTooltips();
    }
});
