I have 2 iframes id="Frame" and id="Frameinfo".
My script is very simple:

Code:
function update(url){
document.getElementById('Frameinfo').src=url
}
This function is activated by
Code:
onLoad="update('inbox.php')"
Now I get tis error:
document.getElementById(...) is null or not an object

What am I missing here?

check that the id of id=Frameinfo is indeed Frameinfo and id="Frameinfo" is not repeated in the document.

Allow me to give you the full code:

Main page code (Parent window):

<center><iframe name="Frame" id="Frame" SRC="blank.html" width=950 height=60 frameborder=1 marginwidth=0 marginhight=0 frameborder=0 Scrolling="no"></center>
<center><iframe name="Frameinfo" id="Frameinfo" SRC="blank.html" width=950 height=420 frameborder=1 marginwidth=0 marginhight=0 Scrolling="yes"></center>

Code in iFrame id=Frame:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<html>
<head>
<title>Untitled</title>
<script language="Javascript">
function update(url){
document.getElementById('Parent.Femeinfo').src=url
}
</script>
</head>

<body bgcolor=#a5b395 onLoad="update('Inbox.php')">
<br>
<table border=1 width=930>
<tr>
<td width=40 height=30>
<b><center>Urgent</center></b>
</td>
<td width=450>
<b><center>Subject</center></b>
</td>
<td width=250>
<b><center>From</center></b>
</td>
<td width=150>
<b><center>Time Posted</center></b>
</td>
<td width=40>
<b><center>Read</center></b>
</td>
</tr>
</table>

</body>
</html>

I hope this will help. I am totaly lost nd new to javascript.

Change this line

document.getElementById('Parent.Femeinfo').src=url

to

parent.document.getElementById('Frameinfo').src=url

see if that works

Irrelevant to your problem, I would also like to point out with your
<script language="Javascript">
to use the following instead:
<script type="text/javascript">
