Quick Question - Please Help

[mitchell]

OK, so I was looking at a script and decided to use it but have a problem.

<script type="text/javascript">

iens6=document.all||document.getElementById
ns4=document.layers

//specify speed of scroll (greater=faster)
var speed=5

if (iens6){
document.write('<div id="container" style="position:relative;width:175px;height:160px;border:1px solid black;overflow:hidden">')
document.write('<div id="content" style="position:absolute;width:170px;left:0;top:0">')
}
</script>

<ilayer name="nscontainer" width=175 height=160 clip="0,0,175,160">
<layer name="nscontent" width=175 height=160 visibility=hidden>

<!--INSERT CONTENT HERE-->

<!--END CONTENT-->

</layer>
</ilayer>

<script language="JavaScript1.2">
if (iens6)
document.write('</div></div>')
</script>

<table width="175px"><td><p align="right">
<a href="#" onMouseover="moveup()" onMouseout="clearTimeout(moveupvar)"><img src="up.gif" border=0></a>  <a href="#" onMouseover="movedown()" onMouseout="clearTimeout(movedownvar)"><img src="down.gif" border=0></a></p></td>
</table>

<script language="JavaScript1.2">
if (iens6){
var crossobj=document.getElementById? document.getElementById("content") : document.all.content
var contentheight=crossobj.offsetHeight
}
else if (ns4){
var crossobj=document.nscontainer.document.nscontent
var contentheight=crossobj.clip.height
}

function movedown(){
if (iens6&&parseInt(crossobj.style.top)>=(contentheight*(-1)+100))
crossobj.style.top=parseInt(crossobj.style.top)-speed+"px"
else if (ns4&&crossobj.top>=(contentheight*(-1)+100))
crossobj.top-=speed
movedownvar=setTimeout("movedown()",20)
}

function moveup(){
if (iens6&&parseInt(crossobj.style.top)<=0)
crossobj.style.top=parseInt(crossobj.style.top)+speed+"px"
else if (ns4&&crossobj.top<=0)
crossobj.top+=speed
moveupvar=setTimeout("moveup()",20)

}

function getcontent_height(){
if (iens6)
contentheight=crossobj.offsetHeight
else if (ns4)
document.nscontainer.document.nscontent.visibility="show"
}
window.onload=getcontent_height
</script>

How can I get rid of the 100px space at the bottom?

I'm just guessing:

function movedown(){
if (iens6&&parseInt(crossobj.style.top)>=(contentheight*(-1)+100))
crossobj.style.top=parseInt(crossobj.style.top)-speed+"px"
else if (ns4&&crossobj.top>=(contentheight*(-1)+100))
crossobj.top-=speed
movedownvar=setTimeout("movedown()",20)
}

But, it's an educated guess. I'm also guessing that under some circumstances, that extra 100 pixels might come in handy. But, just for fun, try changing it to 20 or 150 or whatever.

Sorry, but I tried that already. Didn't do anything but allow the scroll to continue on forever.

[jscheuer1]

Funny, I just tried and 150 seemed perfect.
