I have managed to produce a dnn skin for my first web site

I install it on a dummy server set up I use as a sandbox - this runs dnn 4.3.0, SQL  server 2005 and iis 6

When I install the skin - which has no containers - on my dev set up - dnn 4.3.1 SQL 2005 and iis 5 I get an error when I apply the skin

It occurs when scrolling - an jav script error box pops up and says top scroll object is invalid/missing or null

The scroll occurs but i have to reset to default skin - where the site then behaves normally - if i persist with the problematic skin it still shows the same problem even when containers are set

Debugging the code seems to be in core java script routine

 

Any what I'm doing wrong anyone??

Applogies I have just got back to the machine with the problem and realise this hasnt been reported properly the error reads

Runtime Error

Line 46

Error:'ScrollTop' is null or not an object

It claims to be an unhandled exception in dnncore.js

function __dnn_bodyscroll()

{

var oF=document.forms[0];

if (__dnn_ClientAPIEnabled() && __dnn_m_bPageLoaded)

oF.ScrollTop.value=document.documentElement.scrollTop ? document.documentElement.scrollTop : dnn.dom.getByTagName("body")[0].scrollTop;

}

i have changed it to

function __dnn_bodyscroll()

{

var oF=document.forms[0];

if (__dnn_ClientAPIEnabled() && __dnn_m_bPageLoaded)

if( oF.ScrollTop != null)

oF.ScrollTop.value=document.documentElement.scrollTop ? document.documentElement.scrollTop : dnn.dom.getByTagName("body")[0].scrollTop;

}

 which seems to stop the error but hardly a quality solution - unless it is the problem

Error:'ScrollTop' is null or not an object

I'm getting this exact same error. I didn't realize it had anything to do with skins. I just installed version 4 and accepted the default skins. Should I just find function __dnn_bodyscroll() and make the changes you made?

I have no idea what I'm doing. I saw DNN demo'd at a conference recently and decided to download it to see if it was a solution to our problem with Snitz Forums. (We need to use NT Authentication and Snitz doesn't support it through AD on a Windows Server 2003 box.) Anyway, I'm having issues. It seems awfully "flaky" and it's very slow. I freely admit that I don't have a clue what I'm doing, though. If anybody can help with that error or offer advice, I'd appreciate it!

This error is usually because you have inserted a <Form> tag in your html.

ASP.Net (and therefor DNN) only allows  one HTML form element per page, and DNN already puts that one in.

What if I desperately want to add bog standard HTML mail capture form that posts to an external site (in this particular case aweber.com) ? I also tried the text/html module and realize the problem.

I realize that I can use an IFrame or do some coding to capture the form and fake a form post it under the hood BUT both methods have disadvantages.

Any other way? I was thinking maybe some hack involving  the .NET 2  ability to crosspost?
