Hi  
Im trying to figure out how to make selection list work  
My example for this is a Real estate web site  
download the code here: [http://www.qcm.co.il/real-estate.rar](http://www.qcm.co.il/real-estate.rar)

I have a table named “assets” and a table named “settlements”  
and a relationship between them

`execute "alter table assets add constraint
fk_asset_settelments foreign key (settelment_id) references
settelments(id)"`

in \_form.rhtml the code is:

[CODE]

Settelment  
  
\<%= collection\_select(:asset, :settelment\_id,  
Settelment.find(:all, :order =\> “settelment”), :id, :settelment,  
options ={:prompt =\> “select”}, :class =\>“settelment”) %\>

[/CODE]

when I try to update an asset settelment I get this error:

[QUOTE]NoMethodError in AssetController#update

undefined method `settelment\_id=’ for #Asset:0x478694c  
RAILS\_ROOT: ./script/…/config/…
