    <p>I'm going to try my best to ask this question without a huge wall of code. Basically I have written a very simple math quiz game. In this game you select a difficulty, the number of questions you want, and the game starts. It asks that number of questions and then you get a score and then the game is over. However, you can restart the game. When you restart, it simply returns you to the home screen, then you can select your options again. The only problem is, we need to keep track of the number of questions remaining in the quiz, the first time around, it works well. We pass <code>numQuestions</code> to the game function. The second time, however, even if I pass <code>numQuestions=10</code>, the value remains 0 from the first time I played the game. Here is the game function:</p> <pre><code>function startGame(difficulty,numQuestions,score){ // begins game, excluded that come its just some acsii art // asks question var q = new question(difficulty); $("#gameInside").html(q.string); $("#gameInside").data('answer',q.answer); // gives answer options for (var ii=0;ii&lt;=3;ii++){ $("#answers").append("&lt;button class='answerButton'&gt;"+q.answerArray[ii]+"&lt;/button&gt;") } // starts timer var b = document.getElementById("timer"); timer = new stopWatch(b, {delay: 100}); timer.start(); },5500) // when answer is clicked, go here $("#gameScreen").on("click",".answerButton",function() { // this seems to be the problem: on the second time I play the game, numQuestions remains the value from the first game and continues to go down (-1,-2) and since my selector is (&gt;0), the else statement fires. numQuestions--; var time = parseFloat($("#timer span").html()); var correct = parseFloat($("#gameInside").data('answer')); var userAnswer = parseFloat($(this).html()); if (correct==userAnswer) tempScore = Math.round(calculateScore(time)*100)/100; else tempScore = 0; score += tempScore; $("#score").html(Math.round(score*100)/100); if (numQuestions &gt; 0) { var q = new question(difficulty); $("#gameInside").html(q.string); $("#gameInside").data('answer',q.answer); $("#answers").empty(); for (var ii=0;ii&lt;=3;ii++){ $("#answers").append("&lt;button class='answerButton'&gt;"+q.answerArray[ii]+"&lt;/button&gt;") } timer.reset(); } else { $("#answers").empty(); $("#gameInside").html('Game Over! Thanks for Playing!'); timer.stop(); } }); } </code></pre> <p>any ideas? Thanks</p> <p>edit:</p> <pre><code>$(".numberQButton").click(function(){ numQuestions = parseFloat($(this).html()); $("#numQuestionsScreen").hide(); $("#gameScreen").show(); $("#score").html(0); startGame(difficulty,numQuestions,score); }); </code></pre>

    1. COWhere are you calling startGame? Where is your numQuestions defined?

    2. COedited: It seems like after one game, it begins to fire both correctly and incorrectly, as if there are two versions of the variable... I screwed something up

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.
