I am preparing a skin for DNN version 5.1.2 . There is an image on the skin. When some one clicks on the image it shows a dropdown list. The click event is implemented through JQuery. The problem that I am facing is that when I open the .htm file in the browser (IE or Firefox) it works fine. When I make it the part of skin it does nothing. even No error is displayed on the status bar. Can any one help me?

I can point you to some useful resources on using jQuery with DotNetNuke: Will Strohl's blog (willstrohl.com) and Joe Brinkman's blog (at dotnetnuke.com). For me, jquery is still a future task.
