Sorry, thought it was obvious from that code snippet and it's important 
to show how the javascript is generated differently depending on the 
context.

The problem has been fixed by putting

<A HREF="javascript:jah('something.cgi', 'contentdiv')>click to load</A>

inside <div id='contentdiv'> rather than outside.

I have no idea why this fixed it.  This is the only change made but now 
I'm getting no further errors from getElementById when calling the ahah 
function directly.

I checked that angle out as well.  didn't matter where the target div was 
placed in relation ship to the ahah call.

Not sure why it works not, but at least it works.
