Problem accessing content using Javascript

Hi,

I'm trying to integrate FCKeditor into an asp.net application. What I need to be able to do is simply to get the html from FCKeditor. I have tried working it out from the documentation and from searching on here but am still unable to get it to work and baffled as to why.

I have spent several hours trying on this, but where I am currently is as below:

The editor is integrated with:

<FCKeditorV2:FCKeditor ID="FCKeditor1" runat="server"></FCKeditorV2:FCKeditor>

Then in javascript I get 'FCKe is undefined':

function getMyContent() {
    var FCKe = FCKeditorAPI.GetInstance("ct100_ct100_FCKeditor1");
    return FCKe.GetHTML();
}

Any help would be much appreciated!
