RUby on rails if else syntax confusion

having trouble with the if else -- I am thinking it is a syntax issue but I can not seem to get it. I used the suggestions below and it is still throwing a 500 error. I do not know the exact error because there is a custom error message and "a 500" is the only technical information given. is there a debug mode that I can enable on the dev side that would provide additional information?

What I am trying to do is display a drop down and allow for a selection if you are a "DSD" otherwise the drop down should be disabled, which is why I need the IF statement.

Here is the current if statement that I am running:

Updated

        <% 
           if (sign_on.acctypw1.strip =="DS") 
               select_tag(:distributor_number_X,  options_for_select(distributors_array), {:style => "width:400px", :disabled => "true"}) 
           else (sign_on.acctypw1.strip =="DSD")               
               select_tag(:distributor_number_X, options_for_select(distributors_array), {:style => "width:400px" })
           end
        %>

here is the error from the server log:

You want to use elsif instead of else there.

You also need to wrap your if/elsif/end in <% %> tags as this is ERB

<%= 
   if (sign_on.acctypw1.strip =="DS") 
       select_tag(:distributor_number_X,  options_for_select(distributors_array), {:style => "width:400px", :disabled => "true"}) 
   else (sign_on.acctypw1.strip =="DSD")               
       select_tag(:distributor_number_X, options_for_select(distributors_array), {:style => "width:400px" })
   end
%>

I assume this is in your view (erb.html file) Your if and else statements also have to go inside <% %>.

<% if sign_on.acctypw1.strip =="DS" %>
  <%= select_tag(:distributor_number_X, options_for_select(distributors_array), {:style => "width:400px", :disabled => "true"}) %>
<% else sign_on.acctypw1.strip =="DSD" %>             
  <%= select_tag(:distributor_number_X, options_for_select(distributors_array), {:style => "width:400px" })  %>
<% end %>

Also, something to keep in mind --

<% "This will be evaluated" %>
<%= "This will be evaluated and outputted to your view" %>
