In [EMAIL PROTECTED] you are calling the *year* method of the * @risks.LastReviewed* object which, I assume, is of class *Time* . if that object is nil then it is no longer a Time object... it is a nil object of type NilClass <http://www.ruby-doc.org/core/classes/NilClass.html> .. and you can only call NilClass methods for it. > > > Anyhow...you help was great and has allowed me to sort the problem so > thanks very much indeed. > > Just for anyone else....I also needed to put the existance check in the > displayed element of the drop-down selection thus:- > > <option value="<%= @risks.LastReviewed.year if @risks.LastReviewed%>" > selected="selected"><%= @risks.LastReviewed.year if > @risks.LastReviewed%></option> > > Martyn > > -- > Posted via http://www.ruby-forum.com/. > > > > -- Mahmoud Said Software Developer blog.modsaid.com www.eSpace.com.eg +20-16-1223857 --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
