posting invoice via API

LSMB 1.2 Beta 2

I'm trying to post an invoice via the API in LSMB 1.2.  Every time I do 
so, though, it seems to think I'm using a web browser and returns a 
screen full of html.  Here's what I have:

./is.pl "path=bin/mozilla&
login=bootscootin&
password=boogie&
action=post&
customer=me&oldcustomer=me--51703&
customer_id=51703&
AR=1200&
currency=USD&
defaultcurrency=USD&
employee=Server--10157&
invnumber=chucktest&
transdate=11-23-2006&
duedate=11-26-2006&
partnumber_1=1823100&
description_1=Tricked Out Computer&
qty_1=1&
sellprice_1=4000.00&
id_1=17425&
income_accno_1=10045&
taxaccounts_1=2150&
notes=Invoice posted from the command line&
rowcount=2"

The product exists.  The customer exists.  There is no error returned 
within the html.  It just adds 3 form entries for parts instead of 2 and 
the invoice is not posted.  What am I doing wrong?
