</div>

In one of my forms, I have 2 date input fields (start\_date and  
end\_date) each one depending on the other ( need to add/substract  
variable period)

I wrote that , but how the methods start\_changed or end\_changed can  
modify the date value to add/sbstract a period before the replacement  
of teh corresponding div… ?

\<%= link\_to\_remote(“starting\_date”, :update =\> ‘dd\_enddate’, url =\>  
{:action =\> :start\_changed} ) %\>  
  
Booking Start Date  
  
\<%= text\_field “bookings”, “startdate”, options = {:class =\>  
‘format-d-m-y’, :maxlength =\> “15” } %\>

\<%= link\_to\_remote(“starting\_date”, :update =\> ‘dd\_startdate’, url =\>  
{:action =\> :end\_changed} ) %\>  
  
Booking End Date  
  
\<%= text\_field “bookings”, “enddate”, options = {:class =\>  
‘format-d-m-y’, :maxlength =\> “15” } %\>

or should I use a form\_remote\_tag ? but these 2 fields area already  
within a form … does it matter ?

thanks for your help
