check_box_tag nightmare

I have been struggling to get some check boxes working but have had absolutely no luck. Can someone tell me what I am doing wrong. Any help would be greatly appreciated.

Here is the code in my view:

    <% for size in @sizes %>         <%= f.check_box('size_list', size, @item.sizes.collect {|size| size.id}.include?(size.id)) %><%=h size.name %><br />     <% end %>

Here is the code in my controller:

    @brands = Brand.find :all     @sizes = Size.find :all     @categories = Category.find :all     @item = Item.find(params[:id])

The error I get is:

Showing items/edit.html.erb where line #15 raised: undefined method `check_box_tag' for #<ActionView::Helpers::FormBuilder:0x7f5ca4ed2e90>

PS: I've tried it with check_box_tag and check_box both.

Here is the code in my view:

   <% for size in @sizes %>        <%= f.check_box('size_list', size, @item.sizes.collect {|size| size.id}.include?(size.id)) %><%=h size.name %><br />    <% end %>

Is that all code in the view, or do you have form_for here also?

Here is the entire view as I have it now. I did manage to get the check boxes to show up finally but once you submit the form and come back to the view again to check that the information was saved correctly they are all messed up. For example I have three sizes in my database (10,11, and 12) and the first time you view the form these are the three options shown but if you select anyof the and submit the form when you refresh the form they all three have the same label (12 in my case). I'm just plain confused here.
