Having everything in a loop makes it hard to read your code.
You need a contact id to attach a response to.
Here's a brief overview of how I'd do it:
loop through contacts
row begins
display contact info
display response form
row ends
end loop
response form:
give it a post method
add a hidden contact id field <--
response input (text)
submit button
Form processing logic:
if this is a post request, and we have an id and response:
do your SQL update
I'd place the form processing out the loop at the top of your script, or on another page.
