Getting a Form To Work

Sun Jul 19 11:35:58 EDT 2009

Hi;
I have the following in a *.py page for the Web:

from primeNumbers import primeNumbers

try:
  num = form.getfirst('num')
except:
  num = ''
  msg = "Oops"

print "Content-Type: text/html"
print
print """
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "
http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">
<head xmlns="http://www.w3.org/1999/xhtml">
</head>
"""
if num != '':
  try:
    num = round(float(num))
    roots = primeNumbers(num)
    print roots
  except:
    msg += "We're sorry! You entered something that is not a number. Please
try again.<br />\n"
    num = ''
if num == '':
  print msg
  print "Num:", num
  print """
<form action="http://13gems.com/test-Calculators_frame.py" method="post">
<input type="text" name="num" size="20" maxlength="20" value="Enter number
here..." onfocus="this.value=''" />
<input type="image" src="http://13gems.com/images/search.jpg" name="search"
id="search" />
</form>
"""
print '</body></html>\n'

Now, "Oops" never gets printed, nor does the variable num (although a blank
space appears to print). I am calling the very page to which the form sends
its values. Assuming the imported module works, why don´t I get anything
printed?
TIA,
Victor
