SharePoint 2007 (Gov hasn't Migrated to 2010 yet)
I'm not sure what is going on with this custom form. I have made custom disp, edit and new forms for my work and had to add the save/cancel button. Well the cancel button works fine it's the savebutton that has issues. Here is the code I used:
<SharePoint:SaveButton runat="server" ControlMode="New" id="newsavebutton"/>
The error I get is below:
Server Error in '/' Application.
