I have this select statement, trying to change to a page that is the  
value of the select:

\<%= select(:node, :id, $shelves,{:prompt =\>‘Select Equipment’},  
{ :onchange =\> "document.location.href = ‘/buildshelf/’ + $F('node\_id  
').value + ’ "} ) %\>

How do I make this happen?

</div>

What is the HTML that is rendered from that?

Can you see the problem there in the rendered HTML?

Well I did this:  
:onchange =\> "document.location.href = ‘/buildshelf/’ + $F  
(‘node\_id’).value + "

for the onchange part and I get this for html, still puzzled:

</div>

couldn’t you just do something like:

onchange=“document.location.href = ‘/buildshelf/’ + this.value”
