Editing entries with Channel Form not working

Question

I've created a bunch of simple entries for a channel, and I'd like guest users to be able to edit the entries. The entries are all on the index page, since this is a one-page site. No matter what I try, my Channel Form will not update the entries. This is basically straight from the docs, but submitting the form doesn't change any of the fields. Here's my code:

{exp:channel:entries
 channel="products"
 disable="categories|member_data|pagination|trackbacks"
 dynamic="no"
}

<img src="{product_image}" class="pure-img">
    {exp:channel:form channel="products" return="product/index" url_title="{url_title}"}
 <input name="title" type="text" value="{title}">
 {field:product_description}
 <input type="submit" value="Submit">
{/exp:channel:form}

        {/exp:channel:entries}

Thanks for any help!

Answer 1

Take the exp:channel:entries tags away....

Answer 2

change the url_title on the channel form tag

    {exp:channel:form channel="products" return="product/index" url_title="{url_title}"}
 <input name="title" type="text" value="{title}">
 {field:product_description}
 <input type="submit" value="Submit">
{/exp:channel:form}

to url_title="{segment_1}"
