    <p>Lets clarify my question,</p> <p>I want to make an element which the element contains 5 fields so I dont want the user should be able to put in a new element if the old one is null, so I made the alert when looping through the old element and see if there is some strings, if not then dont put a new element and make an alert please fill out all fields</p> <p>Here again my code</p> <pre><code>function addEvent() { var ni = document.getElementById('discount'); // Takes the a div named discount var discountForm = document.getElementById('discountForm'); // Takes the a form named discountForm var numi = document.getElementById('theValue'); // Takes the a hidden input field named theValue var num = (document.getElementById("theValue").value -1)+ 2; // Start counting to set the new divs form numbers numi.value = num; var divIdName = "my"+num+"Div"; // the new divs will be named var allDivTags = discountForm.getElementsByTagName('div'); // take all div tags var numOfDivs = (allDivTags.length -1); // take the number of the old div var oldDivIdName = document.getElementById(allDivTags[numOfDivs].id); // old div id var newdiv = document.createElement('div'); //the new div newdiv.setAttribute("id",divIdName); newdiv.innerHTML = "Company &lt;select name=\"company[]\"&gt;&lt;option value=\"\"&gt;&lt;/option&gt;&lt;option value=\"ZI\"&gt;Avis&lt;/option&gt;&lt;option value=\"ET\"&gt;Enterprise&lt;/option&gt;&lt;option value=\"ZE\"&gt;Hertz&lt;/option&gt;&lt;option value=\"ZD\"&gt;Budget&lt;/option&gt;&lt;option value=\"ZR\"&gt;National&lt;/option&gt;&lt;option value=\"AL\"&gt;Alamo&lt;/option&gt;&lt;/select&gt; Discount Type &lt;select name=\"type[]\"&gt;&lt;option value=\"CD\"&gt;Discount Number&lt;/option&gt;&lt;option value=\"PC\"&gt;Coupon Number&lt;/option&gt;&lt;/select&gt; Code &lt;input name=\"code[]\" type=\"text\"&gt; Title &lt;input name=\"title[]\" type=\"text\"&gt; &lt;a href=\"javascript:;\" onclick=\"removeElement(\'"+divIdName+"\')\"&gt;Remove&lt;/a&gt;"; // creating the fileds in the new div ni.appendChild(newdiv); for(i=0; i&lt;discountForm.elements.length;i++){ // loop through the divs if(numOfDivs != i-1){ // if tho old div exist and if the old div fields are empty if(oldDivIdName.children[i].value.length == 0){ removeElement(divIdName); // then dont put the new one alert('Please enter all fields'); } } } } </code></pre> <p>But my problem is that in IE comes out an error <code>children[...].value.length is null or not an object</code> so I trying to figure how to fix it,</p> <p>I hope its more clearly for you now.</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
