    <p>I have an object constructor function here: </p> <pre><code>function Box (id, name, color, number, coordinates) { this.id = id; this.name = name; this.color = color; this.number = number; this.coordinates = coordinates; this.add = function(howMany) { } } </code></pre> <p>I have part of a function here where I get a numeric value (5,10 or 15) that the user chooses with a radio button.</p> <pre><code> function getBoxValues() { var nameInput = document.getElementById("name"); var name = nameInput.value; var numbersArray = dataForm.elements.amount; for (var i = 0; i &lt; numbersArray.length; i++) { if (numbersArray[i].checked) { number = numbersArray[i].value; if (name == null || name == "") { alert("Please enter a name for your box"); return; } else { var newbox = new Box("id", name, color, number, "coordinates"); boxes.push(newbox); addBox(newbox); var data = document.getElementById("dataForm"); data.reset(); } </code></pre> <p>Later, I add boxes to the page with this function:</p> <pre><code> function addBox(newbox) { var scene = document.getElementById("scene"); var div = document.createElement("div"); div.innerHTML += newbox.name; var x = Math.floor(Math.random() * (scene.offsetWidth-101)); var y = Math.floor(Math.random() * (scene.offsetHeight-101)); div.style.left = x + "px"; div.style.top = y + "px"; scene.appendChild(div); newbox.add(number); for (var i = 0; i &lt; howMany; i++) { console.log("added"); addBox(newbox); } } </code></pre> <p>My problem is that I want to add the same number of boxes to the web page as the user chooses with the radio button. So far, my console log tells me "added" for the number of times that the value of "number" is looped through. But, I don't know how to change my code so that new boxes are created for the value of number. I am a beginner at this, so I apologize in advance for any confusion. Would appreciate any help. </p>

    2. COwhy do you question it? I'm still trying to figure this out, and like I said I'm new at this so it may be obvious to you but it isn't to me

    3. COappending a child to the DOM, then adding that to a function call(that is not listed) and what is "number", where is that declared? makes no sense - please describe your intent there., number appears to be global with no other detail than this.

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.
