Most likely you attempted to do something like

   http {
       fastcgi_param ...
       ...
       server {
           ...
           location ... {
               fastcgi_param ...
               ...
           }
       }
   }

This won't work due to inheritance rules for array-type 
directives, see here:

http://wiki.nginx.org/NginxHttpFcgiModule#fastcgi_param

"Directives set in current level clear any previously defined 
directives for the current level."

You have to define all fastcgi_param directives at the same level, 
i.e. 

   location ... {
       fastcgi_param ...
       fastcgi_param ...
       ...
   }

or

   http {
       fastcgi_param ...
       fastcgi_param ...
       ...
   }
