  Hi,
I'm learnning cgi and html  having a bit of a problem passing values to 
my cgi script.
Here is the first script:
========================================
#!/usr/bin/python

theSalesOrder = """Content-type: text/html\n
<html>
<head>The Test</head>
<body>
<form method=get action="/cgi-bin/saleOrderAddProc.py">
<p>Customer PO #:</p>
<input class="customerPONbr" type=text name=customer</input>
<p><input type=submit></p>
</form></body></html>"""

print theSalesOrder
=========================================

Here is the script that is called my the script above:
-------------------------------------------
#!/usr/bin/python
import cgi, sys
sys.stderr = sys.stdin

theSalesOrder = """Content-Type: text/html\n
<html><head><title>
my test
</title></head>
<body><h4>%s</h4>
</body></html>"""

form = cgi.FieldStorage()
line1 = form['customer'].value

print theSalesOrder % (line1)

----------------------------------

I'm running Redhat 7.1 with the lastest release of mozilla, althought I get
my error if I use Netscape 4.X, and I'm using Apache 1.3.20.
Here the error from apache's error-log:

[wayne at localhost online-ledger]$  tail  /usr/local/Apache/logs/error_log
Traceback (innermost last):
  File "/usr/local/Apache/cgi-bin/saleOrderAddProc.py", line 13, in ?
    line1 = form['customer'].value
  File "/usr/lib/python1.5/cgi.py", line 907, in __getitem__
    raise KeyError, key
KeyError: customer

When I enter data in the first script  and submit it, I set the 
following URL address in my browser;
http://localhost/cgi-bin/salesOrderAddProc?customer%3C%2Finput=data entered
If I remove the %3C%2Finput and run that it works.

WHAT AM I DOING WRONG?
Thanks Wayne.
