    <p>I'm trying to create an alert in JavaScript using cookies that both greets the user by name and tells them how many times they've won a specific game on the website. I have the user greeting working fine, but I can't seem to get the counter to work correctly. It involves calling variables that are altered by a previous function, and I think that's where my problem is, but I'm not sure how to fix that. (The variables are called 'cardOnePoints' and 'cardTwoPoints'.) Can anyone help me with that or tell me if there's anything else I'm doing wrong?</p> <pre><code>function getCookieOne(c_name) { var i,x,y,ARRcookies=document.cookie.split(";"); for (i=0;i&lt;ARRcookies.length;i++) { x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("=")); y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1); x=x.replace(/^\s+|\s+$/g,""); if(x==c_name) { return unescape(y); } } } function setCookieOne(c_name,value,exdays) { var exdate=new Date(); exdate.setDate(exdate.getDate() + exdays); var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString()); document.cookie=c_name + "=" + c_value; } var winnerCount; var getCount = getCookieOne('getCount'); function winnerCount() { if (cardOnePoints + cardTwoPoints === 21) { winnerCount = getCount + 1 } else { winnerCount = getCount }; } function countWinner() { return winnerCount } function checkCookie() { var username=getCookieOne("username"); var gamesWonCount=getCookieOne("gamesWonCount"); function winnerCounter() { var gamesWin if (cardOnePoints + cardTwoPoints === 21) { gamesWin=++winnerCount; } else { gamesWin=winnerCount }; return gamesWin } if (username!=null &amp;&amp; username!="") { alert("Sup " + username+ "!!! Woah man, you've won " + countWinner() + " game(s)!!!"); } else { username=prompt("Please enter your name:",""); if (username!=null &amp;&amp; username!="") { setCookieOne("username",username,365); } } } </code></pre>

    1. COuse localStorage unless you need to support < IE8. You can store permanent variables like an array: `localStorage["name"] = whateverAskedTheUsersName` http://www.html5rocks.com/en/features/storage

    2. COI'm sorry, I don't understand how that applies to calling these variables after they've been altered?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
