[erlang-questions] yaws crashes

[Salonee Sinha Roy]

Hi
I am trying to write a simple facebook app with iframes using yaws. My code
is below

<erl>
out(Arg) ->
    {ok,User} = queryvar(Arg,"fb_sig_user"),
    case queryvar(Arg,"fb_sig_user_add") of
        {ok,Page} ->
        %% check if the user has added the app
            if
                    Page == "0" ->

{redirect_local,string:concat("/www/terms_cond.html?soc=fb&uid=",User)};
                Page == "1" ->

{redirect_local,string:concat("/www/mask_flash.html?soc=fb&uid=",User)}
            end
    end.
</erl>


When I try going to the page above I get the following error

ERROR erlang  code  crashed:

        {proc_lib,init_p_do_apply,3}]


Any help would be appreciated.
