Rails - Dec 2009 - Simple string comparasons

Hey Everyone I''m caught up on some data output.

this is what i currently have:
<dl class="details">
		<dt>Make:</dt><dd><%=h vehicle.make %></dd>
		<dt>Model:</dt><dd><%=h vehicle.model %></dd>
		<dt>Year:</dt><dd><%=h vehicle.year %></dd>
		<dt>Mileage:</dt><dd><%=h vehicle.mileage
%></dd>

		<% if vehicle.vehicle_options.drive.eql? "please_select" %>
			<dt>Transmission:</dt><dd><%=h
vehicle.vehicle_options.transmission
%></dd>
		<% end %>

		<% if vehicle.exterior_color.eql? "not_specified" %>
			<dt>Ext Color:</dt><dd><%=h vehicle.exterior_color
%></dd>
		<% end %>
		<% if vehicle.vehicle_options.drive.eql? "please_select" %>
			<dt>Drivetrain:</dt><dd><%=h
vehicle.vehicle_options.drive %></dd>
		<% end %>
		<% if vehicle.vehicle_options.engine_size.eql? "" %>
			<dt>Engine:</dt><dd><%=h
vehicle.vehicle_options.engine_size %></
dd>
		<% end %>
		<dt>Price:</dt><dd><%=h vehicle.price %></dd>
	</dl>

I have some enumerated fields on creation and I don''t want to display
them in the event someone has decided not to fill them out (ie leaving
them as the default). The above does not work sadly. How can I
appropriatly check for this. I also have some boolean values as well
as possible nils(Or blank space). How can I check for these and if
theres content display it. Otherwise skip that whole field ?

I figure it should be pretty easy but everything I try fails.

Thanks, Happy Holidays !
