Python CGI script can't write files, permission denied


Ok, I have my python CGI script, and it isn't able to write to my config file (which is named config.cfg). First it wasn't able to open the file at all. So I did a touch config.cfg, and a chmod 777 config.cfg, but still it can't open the file for writing ("Permission denied"). So, since it was in my ScriptAlias directory, I thought maybe that was the problem, so I made a new directory, and put it in that, so now it is in test/config.cfg. It still wont work! I've tried changing users, modes, everything on the file and all the directories leading to the file, but still I get the same error. Anyone got any ideas?

Code:
#!/usr/bin/python

import cgi, cgitb; cgitb.enable()

print "Content-Type: text/html\n\n"     # HTML is following
#print                               # blank line, end of headers

class IncomeChunk:
	Type = 0
	Amount = 0.00
	Description = ""
	
IncomeSplits = []

def LoadCFG():
	global IncomeSplits
	
	try:
		Handle = open("accounting/config.cfg", "rb")
	except:
		print "Error: Unable to open config file for reading"
		return
	
	try:		
		Line = Handle.readline()
		Splits = Line.split(",")
		del IncomeSplits[:]
		for I in Splits:
			Data = I.split(":")
			Chunk = IncomeChunk()
			Chunk.Type = int(Data[0])
			Chunk.Amount = float(Data[1])
			Chunk.Description = str(Data[2])
			IncomeSplits.append(Chunk)
	except:
		print "Error: Unable to load configuration"
		return
	Handle.close()
		
def SaveCFG():
	global IncomeSplits
	
	Handle = open("accounting/config.cfg", "wb")
	#except:
	#	print "Error: Unable to open config file for writing"
	#	return
		
	for I in IncomeSplits:
		if I != IncomeSplits[0]: Handle.write(",")
		Handle.write("%d:%f:%s"%(I.Type, I.Amount, I.Description))
	Handle.write("\n")
	Handle.close()

Form = cgi.FieldStorage()
Action = Form.getvalue("_cmd")		
print "<html><body bgcolor=\"#205fd4\" text=\"#ffffff\">"
LoadCFG()

if Action == "add_split":
	Amount = Form.getvalue("amount")
	Description = Form.getvalue("description")
	if '%' in str(Amount):
		Chunk = IncomeChunk()
		Chunk.Type = int(0)
		Chunk.Amount = float(Amount.strip("%%"))
		Chunk.Description = str(Description)
	else:
		Chunk = IncomeChunk()
		Chunk.Type = int(1)
		Chunk.Amount = float(Amount)
		Chunk.Description = str(Description)
	IncomeSplits.append(Chunk)
	SaveCFG()
	
print "<table border=\"1\" with=\"100%%\">"
print "<tr>"
print "<td>"
print "Amount - Amount of money for this split (put a %% for a percentage)"
print "</td>"
print "<td>"
print "Description - Description of split &nbsp;&nbsp;&nbsp; "
print "</td>"
print "<td>"
print "</td>"
print "</tr>"
Index = 0
while(Index < len(IncomeSplits)):
	I = IncomeSplits[Index]
	print "<form method=\"post\" action=\"accounting.py\">"
	print "<tr>"
	print "<td>"
	if I.Type == 0:
		print "<input type=\"text\" value=\"%s%%\" name=\"amount\">"%str(I.Amount)
	elif I.Type == 1:
		print "<input type=\"text\" value=\"%s$\" name=\"amount\">"%str(I.Amount)
	print "</td>"
	print "<td>"
	print "<input type=\"text\" value=\"%s\" name=\"description\">"%I.Description
	print "</td>"
	print "<td>"
	print "<input type=\"submit\" value=\"Edit\">"
	print "</td>"
	print "</tr>"
	print "<input type=\"hidden\" name=\"_cmd\" value=\"edit_split\">"
	print "<input type=\"hidden\" name=\"_index\" value=\"%d\">"%Index
	print "</form>"
	Index = Index + 1

print "<form method=\"post\" action=\"accounting.py\">"
print "<tr>"
print "<td>"
print "<input type=\"text\" value=\"\" name=\"amount\" size=\"50\">"
print "</td>"
print "<td>"
print "<input type=\"text\" value=\"\" name=\"description\" size=\"100\">"
print "</td>"
print "<td>"
print "<input type=\"submit\" value=\"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Add&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\">"
print "</td>"
print "</tr>"
print "<input type=\"hidden\" name=\"_cmd\" value=\"add_split\">"
print "</form>"
print "</table>"
print "</body></html>"

That is my complete script, however the problem is in SaveCFG. It is going to be a script to help me split my income into percentages or raw amounts.

Have you tried changing up the modes on your Handles?

Handle = open("accounting/config.cfg", "w")

Also, and this may not make a difference, try putting the full path to config.cfg. I've had some issues with the open method as well and it seems to be very picky at some times.
