Herein lies my problem. Not only do I not know how to check if a form has
been submitted (without searching for the information in the database, which
doesn't seem efficient), but I've been unsuccessful in stopping the
submittal. I've attempted to use javascript for submitting the form (or not)
with: "formname.submit()" but that hasn't worked for me. Every time the page
is refreshed, the information is posted and hence, submitted.
