</div>

This might be more of an HTML general question, but I have been trying  
to find a “rails” way to do this and have come up short. What I want to  
do is to have a div appear if a certain selection from a drop-down is  
selected or dissapeare if another option is selected. Here is what I  
have:

 \>Admin onselect = "alert('TEST'); document.getElementById('agency\_admin\_div').style.display = '';"\> Agency Admin \>Agent \>Travel Manager \>Traveler

This doesn’t work, and I have been unable to find an oppropriate rails  
or html example that gives me what I want. I have done similar things  
with rails helpers before but never with the “select” tag. Anybody have  
any suggestions? Thanks,
