Could someone tell me what I did wrong with this script. It should read
the page
http://www.mto.gov.on.ca/english/traveller/conditions/rdclosure.htm and
only read between the 2 words in the script. And email any new stuff to the
email address in the script. What did I do wrong that is causing this
script to fail?
