Hi,

Just started back up with html. I have a website folder where I have my index.html file, my main.css, images, and events.js. I cannot get my java script to load correctly. Please help.

I will attach my index.htm file for viewing in your own editor or I will post below. Thanks!

It's this one, right?
http://www.javascriptkit.com/script/script...scalendar.shtml

Why not paste the bits and pieces in again since the script downloaded from there works?

I see a comment is messed upp here:
CODE
/ ********************************************************************************

*******


A multi line comment begins with /* and ends with */ . The space between the first / and the first * shouldn't be there and it isn't in the original script. Alas, that doesn't fix the problem, but it's probably part of it.

Well thats what i did. i copied and pasted from the source code from that site. So i see that if fixing the comment doesnt fix it, then where did I go wrong. I feel im pretty close but obviously off.

Obviously you did a little more than that. That space didn't get there on its own. wink.gif

Did you put events.js where it should be? I suspect you didn't.

<script language="JavaScript" type="text/javascript" src="events.js"></script>

Obviously you did a little more than that. That space didn't get there on its own. wink.gif

Did you put events.js where it should be? I suspect you didn't.

CODE
<script language="JavaScript" type="text/javascript" src="events.js"></script>



Ya the events.js file is in the same folder as index.

could it possibly be that the images for the script arent loading? I have a images folder that came with the download that has the images inside it. but when i read the script is says myimages and i cant see where the script is grabbing the images from. idk. maybe thats not it. hoping someone can solve this. im quite perplexed

No, the calendar isn't images. Fact is that what you posted works when I connect it to events.js .
