Updating postitions in an acts as list model, with tet fields...

Hey all.

I'm trying to copy this example I found, which I'm assuming no longer works.... that or I'm stupid... I want to have the position for each "row" show up ina box, with a "update position" button that submits the form, and updates the position... in retropect I shuld have used the Draggable effect in Scriptaculous, it would have been faster. Anyway, now I'm wondering how I would do this... Any help would be great.

I get a parameter that holds everything I want

{"commit"=>"Update Positions", "rate_group_additional_rate"=>{"1488"=>{"position"=>"6"}, "948"=>{"position"=>"1"}, "949"=>{"position"=>"2"}, "1396"=>{"position"=>"5"}, "950"=>{"position"=>"3"}, "951"=>{"position"=>"4"}}}

where rate_group_additional_rate is the model's position I want to upgrade.
