I am trying to get a div to show when a radio button is clicked but  
the problem is that the div is dynamically named. I am using the  
normal html for a radio button:

Because observe field does not work well with radio buttons. I have  
tried adding an onclick with the div id:

But the #{@appt\_to\_edit.id} does not get rendered and I have had a lot  
trouble figuring out how to do this. I think I need to use some sort  
of inline RJS? Im not sure, does anyone have any ideas?

').show()"\>

this should do it. You are inside HTML code and not inside a ruby  
string, so the #{} syntax won’t work. Instead you have to use the Erb  
sequence \<%= %\>
