I want to know how to get the id of the dropped-in-element. I already  
have this code:

\<%= drop\_receiving\_element(“drop”, :onDrop =\> “function() { set\_image  
(), delete\_drag(element.id) }”) %\>

but its not working. Firebug tells me that element is not defined -  
why that? Any ideas how to fix it?
