Many thanks to anyone willing to assist.

I have a rails database application that produces about 20 pages showing  
10 lines each. I’d like a link at the bottom to each page that looks  
like many you have seen: Go to page 1 | 2 | 3 | 4 | etc.

Tried to use the “each” method as follows:

\<%= if @member\_pages.each  
link\_to ‘Go to page \>’, { :page =\> ()}  
end  
%\>

I get an error “no block given”

The following snippet:

\<%= if @member\_pages.current.next  
link\_to ‘Next page’, { :page =\> @member\_pages.current.next }  
end  
%\>

DOES produce a link to the next page! But I didn’t figure this out. It  
was part of the tutorial. I’d appreciate any help. I bought every book  
on the subject, but I’m too new to know what I’m reading.

Thanks in advance!

You have a basic syntax error - missing the “do” keyword:

Thanks Justin. I dropped the conditional and tried this:

\<%= link\_to ‘Go to page \>’, { :page =\> @member\_pages.each do () end} %\>

This did not produce an error message, but it also did not produce what  
I wanted. Instead, it produced a link to the last page.

Well a few more hours of searching the web produced this excellent link.
