Hi, I am trying to follow this tutorial:

I get the error message: "TypeError: childBrowser is undefined"

Code:
	<script type="text/javascript" charset="utf-8" src="ChildBrowser.js"></script>
            <script type="text/javascript" charset="utf-8">
                	                var childBrowser;
                	                function onBodyLoad()
                	                {
                    	                    document.addEventListener("deviceready",onDeviceReady,false);
                	                }
                	                /* PhoneGap has been initialized and is ready to roll */
                	                function onDeviceReady()
                	                {
                    	                var phoneGapReady;    
                                        phoneGapReady.innerHTML = "PhoneGap is Ready";
                    	                    childBrowser = ChildBrowser.install();
                	                }
                	                function openChildBrowser(url)
                	                {
                    	                    try {
                        	                        //both of these should work...
                        	                        //window.plugins.childBrowser.showWebPage(url);
                        	                        childBrowser.showWebPage(url);
                    	                    }
                    	                    catch (err)
                    	                    {
                        	                        alert(err);
                    	                    }
                	                }
                	                </script>
