    <p>I'm having a bit of trouble getting my head around this thing so I thought it might help to post it here. So here it goes.</p> <p><strong>What I have:</strong> 5 different images in 5 different table cells + a script that I will post below.</p> <p><strong>What I want:</strong> to use the javascript's...</p> <pre><code>document.GetElementById("image ID").style.visibility='visible/hidden' </code></pre> <p>...after a preset time, but, instead of image ID there is a string that gets the ID of the image, and before anyone says anything, I am not using "" for the string that is inside of (). Something like...</p> <pre><code>var n=1; function picID() { pictureID="pic"+n; n=n+1; } </code></pre> <p>...and this way, every time that function is called we get the element ID of "<code>pic1</code>", "<code>pic2</code>", "<code>pic3</code>", etc.</p> <p><strong>What my problem is:</strong> the darn thing won't work. The image styling remains the same as I defined it in the img tag. (<code>style="visibility:hidden"</code>)</p> <p>All image ID's are within the img tag, as it should.</p> <p><strong>Here's the whole code:</strong></p> <pre><code>&lt;script&gt; var m=1; function Show() { if (m==6) {m=1;} feat="feat"+m; **document.getElementById(feat).style.visibility="visible";** m=m+1; setTimeout('Show()', 3000); } window.onload = Show; &lt;/script&gt; &lt;script&gt; var k=1; function Hide() { if (k==6) {k=1;} feate="feat"+k; **document.getElementById(feate).style.visibility="hidden";** k=k+1; setTimeout('Hide()', 3000); } window.onload = Hide; &lt;/script&gt; </code></pre> <p>I've separated the code so it'd easier to spot. From what I've seen the only issue is the bold line within the code. I've tested everything else by replacing the <strong><code>document.getElementById</code></strong> with <strong><code>document.write</code></strong>, so I can see that the custom ID string thingy is working fine. It is. An everything else as well.</p> <p>Any suggestions? Thanks.</p>

    1. COYou are overriding the `onload` Show function with the Hide one...

    2. COThis is unrelated, but you *should* pass functions to `setTimeout`, not strings. `setTimeout(Show, 3000);` and `setTimeout(Hide, 3000);`.

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.
