Wired text_field and text_area

I need to return some values to the form
so I do
<%= text_field ‘property’, ‘name’ , :value => session[:property][:name]
%>Name

and the same fo text area
<%= text_area ‘property’, ‘description’, :value =>
session[:property][:description] , “cols” => 30,“rows” => 6
%>Description
<= but here does not work ? why if I switch on
text_field is OK
