I was on a roll until I started customizing the look of what Rails
created for me... I broke something.
########### NoMethodError ###########
You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.each
--------------------------------
I''ve got a member page where I list the current member on the left
with an "Add Member" section in the main body area. When I click
"Add
Member" I get the above message that references the code below.
<ul>
<% for member in @members %>
<li>
<%= link_to member.first_name + " " + member.last_name , { #
link_to
options
:controller => ''members'',
:action => ''edit'',
:id => member
} %>
</li>
<% end %>
</ul>
Thank you all for your help! I''m such a NOOB!

It would appear that I''m going about it the wrong way. I think I need to split the actions up into more than one page... any thoughts?

Re: nil? I don''t know no nil... or maybe I do know nil...

When I click "Add >> Member" I get the above message that references the code below. >> >> <ul> >> <% for member in @members %>''for'' is a wrapper around ''each'', so the problem is that @members is nil. I suspect that it''s something like this: when you add a member, you trigger an action that re-renders the page, after creating the new member, but does not set @members. That would account for the nilness.
