Sure.
BTW, here's a screenshot of the form and the result at:
www.gonefishingguideservice.com/php.htm
For a test, I put in a few spaces and then "s" and then more spaces and
then "o" and then more spaces and then "s" and then I hit submit and the
script processed without an error.
So, I don't see where the eregi_replace() pattern matching is coming into
play.
Thank you.
