one way is to "send new value to server" for your drops
tell them to reset the fields you want to change dynamically in the reset box,
then in the server code embed, you can open your file, read/build your new "desciption" field (using the ID to reread etc), perhaps stuff the result in the session queue
eg: p_web.ssv('cool:descriptionfield', loc:Userfeedback)
( close the file - too!)
then the "desciption" field or a comment or whatever just needs to be referencing that session value ie: p_web.gsv('cool:descriptionfield')
which the reset would cause to update automatically.
