Google didn;t throw too much up on this but I’m sure I’m not the forst  
to have this problem.

\<%= date\_select ‘client’, ‘dob’,  
       :use\_month\_numbers =\> false,  
       :order =\> [:day,:month,:year],  
       :start\_year =\> 1920,  
       :end\_year =\> @this\_year,  
       :include\_blank =\> true %\>

I’ve tried a few variations for the observe\_field (below) but no luck.  
Could anyone shed some light on this, please?

        \<%= observe\_field(“client\_dob”,  
                          :update =\> “age”,  
                          :url =\> { :controller =\> ‘client’, :action =\>  
:age },  
                          :with =\> “‘dob(1i)=’ + escape($(‘dob(1i)’) +  
‘&dob(2i)=’ + escape($(‘dob(2i)’).value) + ‘&dob(3i)=’ +  
escape($(‘dob(3i)’).value”,  
                          :on =\> “changed”,  
                          :frequency =\> 0.3 ) %\>

\<%= observe\_field(“client\_dob\_3i”,

                          :update =\> “age”,

                          :url =\> { :controller =\> ‘client’, :action =\>  
:age },

                          :with =\> “‘dob(1i)=’ +  
escape($(‘dob(1i)’) + ‘&dob(2i)=’ + escape($(‘dob(2i)’).value) +  
‘&dob(3i)=’ + escape($(‘dob(3i)’).value”,

                          :on =\> “changed”,

                          :frequency =\> 0.3 ) %\>

Merci
