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

this is what i currently have:

Make:\<%=h vehicle.make %\>Model:\<%=h vehicle.model %\>Year:\<%=h vehicle.year %\>Mileage:\<%=h vehicle.mileage %\>

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

```

vehicle.vehicle\_options.transmission  
%\>  
\<% 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 %\>

Price:\<%=h vehicle.price %\>

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 !
