"Never mind"...After adding the bit about paypal codes, I remembered reading about this issue before.  I did a search and found some answers.

I'm getting an incorrect display with this error message :

Message: 'ScrollTop' is null or not an object
Line: 46
Char: 3
Code: 0
URI: http://www.nebraskawriters.org/dotnetnuke/js/dnncore.js
 

How do I go about fixing this ?  Version is 4.09.00.   The problem seems to originate with the PayPal code that is inserted into the page.  I tried the code on other html pages and it displays correctly, just not from within dnn. 

I will upgrade eventually.  The site is hosted on GoDaddy and I needed to get it up and running ASAP.  I'm just finishing up on it now, so I need a break :-)

For any one interested..I solved my problem by creating another directory in godaddy's root (dnn resides in the /dnn by default). I created some html pages where I stuffed the paypal  button code for the instances that I needed and then put a link in my dnn module directly to the url of the pages.  It may not be the most elegant solution, but it works. cheers
