Hi If anyone could help me with this issue it will be greatly appreciated. i've look at a few post which explained how to fix my issue but they didn't work for me.

This is the Javascript scroller im working with:
http://www.dynamicdrive.com/dynamicindex2/sagscroller.htm

I've been trying to load this script called SagScroller. I'm able to get one of the scripts to run on one page, but when i try to load two of them on one page only the first one runs.

Can someone specifically and visually show me what to change in order to get both scripts to run?


heres what i have:
located in the body is TWO of these...


<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>

<link rel="stylesheet" type="text/css" href="sagscroller.css">
<script src="sagscroller.js">

</script>




The Javacript that was referenced is attached...
(i know this is more than likely what needs to be changed something to do with ''onload''. If the person helping can tweak it and highlight what was change it will be helpful.)

Hi I am having exactly the same problem!

Although, I didn't think the .js was the problem, it's the same used on the demo's and that shows multiple scrollers. However, I have been wrong before.

Had a moment of clarity, and a sugary cup of tea. The solution is not in the .js, it's in the id="" of each scroller.

So, the CSS needs div#mysagscroller1, div#mysagscroller2 etc.

The .js needs

//SAG scroller demo #1:

var sagscroller1=new sagscroller({
id:'mysagscroller1',
ajaxsource: 'Tasks.txt',
mode: 'manual' //<--no comma following last option
})

//SAG scroller demo #2:

var sagscroller2=new sagscroller({
id:'mysagscroller2',
ajaxsource: 'SalesPerAnnum.txt',
mode: 'manual' //<--no comma following last option

And the Body text needs

<div id="mysagscroller1" class="sagscroller">
</div>

<div id="mysagscroller2" class="sagscroller">
</div>

<div id="mysagscroller3" class="sagscroller">
</div>

I hope that makes sense.

I absolutely positively must thank you for your help. You explained everything well and it works perfectly.
I hope you enjoyed your sugary cup of coffee.

Have a great day. :)
