The process of creating journal entries begins with pre-numbered paper document -- the journal voucher. This document contains:

1. a preprinted unique four-digit numeric source reference number
2. a maximum of six journal entries per voucher. Each journal entry contains:
   1. four digit major account number
   2. four digit minor account number
   3. four digit sub1 account number
   4. four digit sub2 account number
   5. transaction amount (currency)
   6. 50 character text description for each entry
3. the sum of the journal entry transaction amounts (must be zero)

Such a journal voucher appears as:

SRN: 1234				Fiscal Month: 12
General Ledger Account Number				Transaction Amount	Description
Major	Minor	Sub Acct 1	Sub Acct 2
1000	1000	0000	0000	-135.60	Check #456-234-1 for Nov Electricity
8000	6000	0000	0000	135.60	November Electricity Expense
Sum of Transaction Amounts				0.00

Your form should:

• Assure that the source reference number is a four digit number -- no blanks or non-numeric characters
• Check for valid fiscal-month values: 01, 02, 03, ..., 11,12
• Allow for up to six detail journal entries
• Assure that major, monor, sub1 and sub2 each contain four digit numbers
  Blank fields should be zero-filled
  An account number containing ALL zeroes is INVALID
• Transaction amounts should be valid currency numbers
• Description are always optional
• If any of the four account fields (i.e., major, minor, sub1 or sub2) have entries, then there must be a valid transaction amount for that entry
• If a transaction amount is entered, then a valid GL account number must be present
• Check to assure that for the voucher, the sum of the transaction amounts is zero

There should be a clearly labelled "Validate, then Submit" button on the page. When clicked, the VBScript should provide all the ediitng test discussed above. Each type of failure is to be reported to the user and control returned for correction. If the journal voucher passes all the editing tests, the form should be:

1. Converted to an XML string with appropriate tags
2. Submitted to (i.e., action=):

   http://disc-nt.cba.uh.edu/Students/parks/echoxml2.asp

   to test the contents of the form's querystring. This exe program should return the XML string to the user by setting the content-type to txt/xml and returning the querystring as the only text. The result (if IE5 or later) on the browser will be a correctly parsed XML file of the user's data.

A link to assignment #3 page (a3.htm) should be placed on your in your /~your_user_id/public-html/) directory. It doesn't matter whether it is VBScript or Javascript -- just name it a3.htm.
