Sam, Glad the examples helped. I should probably fess up and point out that I mistakenly added an additional newline to that print statement. You only need one, as the print itself will append an extra. So by adding the addition \n, a blank line will be sent to the browser as part of the page content, which shouldn't be a problem for text/html content-types. But as soon as you want to serve up another content-type (eg. image/png) you may run into odd problems. So, the corrected print statement should look like this: print "Content-type: text/html\n" or as described in the docs, http://docs.python.org/lib/cgi-intro.html print "Content-type: text/html" print HTH, Marty > > With that form, it loaded just fine.
