I have made up an example to show everyone how to use the text editor in your ows modules.
Download the attached example below
(TESTED WITH - OWS 2.1.13, DNN 5.1.1, WIN 2003, SQL 2008)
FYI: Here are the basic steps you need to complete to get the text editor working properly:
STEP 1 Modify your "Add" form
Change your text input box from:
to a text editor:
{TEXTEDITOR,frmDescription,frmDescriptionTemp,Form,100%,400}
STEP 2 Modify your "Add" form button
You will need to add some code so that the text editor remembers your variable.
Add this code to the start of your button:
document.getElementById('frmDescription').value=FCKeditorAPI.GetInstance('frmDescription').GetXHTML(true);
so your button looks like:
STEP 3 Modify your "Save" variable
Modify your save variable so it looks like:

STEP 4 Modify your "Edit" form
Change your text input box from:
to a text editor:
{TEXTEDITOR,frmDescription[ID],"\[Description\]",text,600,300}
STEP 5 Modify your "Edit" form button
You will need to add some code so that the text editor remembers your variable.
Add this code to the start of your button:
document.getElementById('frmDescription[ID]').value=FCKeditorAPI.GetInstance('frmDescription[ID]').GetXHTML(true);
so your button looks like:
STEP 6 Modify your "Update" variable
Modify your save variable so it looks like:

Hopefully this will help everone out :)
