Problem with options_for_select

Hi,
I have a problem with the form select. In the value field I have the
generated html…

<%= f.select :brand_id,
options_for_select([[‘Brands’, 0]] +
@search_brands.map { |b| [b.name, b.id]}),
{:id => ‘cbxBrand’, :tabindex => (@tabindex += 1)} %>

This is the html:

<option value="0">Marques</option> <option value="276987689">Activ distribution</option>

Am i forgetting a parameter or something?

Greg

Ok, I find out, it works without the options_for_select
