dear, I just deployed my first rails application and it failed

when I checked the log file on the server, i got the following

ActionView::TemplateError (wrong argument type FalseClass (expected  
Proc)) on line #13 of daleel/\_top.html.erb:  
10:   
11:  
12:

  
13: \<% form\_tag :action =\> :navigate do %\>  
14:   
15: 

any idea why is it behaving like that  
on my localhost  
there is no error in development and production env

thanks

Have a look through the group archives, but I have a vague  
recollection that ruby 1.8.6 p230 does that.

Well  
I do not find any useful info on google search  
I am just wondering why the server fails on this part of the code.  
However, sometimes it works.

Strange???
