Body
You are setting a <code>timeout</code> that says "after 1 second, do X". Your current timeout is actually pretty hard to follow, but it broadly does this in a very tangled way: <ol> <li>Make <code>counter</code> = 4</li> <li>Wait 1 second.</li> <li>If <code>counter != 1</code>, subtract 1 from the counter, disable button, and go back to 2. Continue otherwise.</li> <li>Enable button.</li> </ol> As you can see, you are disabling the button AFTER waiting 1 second, not immediately. I would suggest changing your countdown() method as follows: <ol> <li>Disable button.</li> <li>Make <code>counter</code> = 3</li> <li>If <code>counter > 0</code>, Print "Click again in <code>counter</code> seconds", Subtract 1 from <code>counter</code>, Wait 1 second and go back to 2. Continue Otherwise.</li> <li>Enable button.</li> </ol> That could look like this: (using your code) <a href="http://codepen.io/Goodwine/pen/ChFxp" rel="nofollow">--- Working Example Here!!! ---</a> <pre><code>function countdown() { document.getElementById('btnOne').disabled = true; //3 is more understandable than 4 for your example. var countdownNum = 3; incTimer(); function incTimer() { if (countdownNum > 0) { // Order of statements IS important. // Note the differences in this IF block. document.getElementById('timeLeft').innerHTML = 'Click again in ' + countdownNum; countdownNum--; setTimeout(function(){ // Note that the whole timeout was moved inside, // Imagine this is recursive function, with a delay. incTimer(); }, 1000); } else { document.getElementById('timeLeft').innerHTML = ''; document.getElementById('btnOne').disabled = false; } } } </code></pre> There are better ways to express your code, but I tried to stick as much as possible to your code style.

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.
