Hi I'm trying to set up a layer with text and have it scroll up to allow the user read the remaining content on mouseover action.
the mouseover action can refer to the layer itself or another control layer with perhaps an arrow image.

any help much appreicated as I am a beginner :)

This was a fun one!

I created a small test with a main html that contains an iframe containing text. I added two links ('up' and 'down') which, when moused-over, causes the window inside the iframe to scroll one way or the other (stopping on the onmouseout event).

I know this isn't exactly what you are doing, but you will see the setTimeout(...), clearTimeout(...), and scrollBy(...) functions you can use to do what you want.

In the main html:
Code: 
<html>
<head>
<script>
var winToScroll;
var timeoutObject;
function scrolling(direction)
{
 if(direction == "up")
 {
  [b]winToScroll.scrollBy(0, -10);[/b]
 }
 else
 {
  winToScroll.scrollBy(0, 10);
 }
 timeoutObject = [b]setTimeout("scrolling('"+direction+"')",100);[/b]
}

function quitScrolling()
{
 [b]clearTimeout(timeoutObject);[/b]
}

function loadIframe()
{
 winToScroll = eval("textToScroll");
 winToScroll.location = "textToAdd.html";
}
</script>
</head>
<body onload='loadIframe()'>
<iframe id='textToScroll' width="50%" height="50%"></iframe>
<a href='#' [b]onmouseover='scrolling("up");'[/b] [b]onmouseout='quitScrolling()'[/b]>up</a>&nbsp;
<a href='#' [b]onmouseover='scrolling("down");'[/b] [b]onmouseout='quitScrolling()'[/b]>down</a>
</body>
</html>

Notice how the iframe is loaded when the main html loads (in the BODY tag's onload event) and the iframe itself is captured in a variable (to be used in the scrolling(...) function).

And in textToAdd.html (could be anything, really, as long as there's enough text to require scrolling):
Code: 
<html>
<body>

I don't use Dreamweaver, so I can't speak to that. I can tell you that by replacing the IFRAME tag I included above with:

Code: 
<iframe id='textToScroll' width="50%" height="50%" [b]scrolling='no'[/b]></iframe>

...you can get rid of the scroll bar.

Good luck!
