Bizarre formatting issues building text email with VBScript

[zoehart]

I'm working with VBScript to build a text email message. I'm seeing a variety of bizarre formatting issues. The following lines of code

MT = MT & vbCrLf & "Card Type: " & CardType
MT = MT & vbCrLf & "Credit Card Number: " & objBOWallet.Enc rypt(Payment.[_account_number])
If Not IsNull(Payment.[_expiration_mon th]) Then
MT = MT & vbCrLf & "Expiration Month: " & Payment.[_expiration_mon th]
End If
If Not IsNull(Payment.[_expiration_yea r]) Then
MT = MT & vbCrLf & "Expiration Year: " & Payment.[_expiration_yea r]
End If
MT = MT & vbCrLf & "Payment Amount: " & Context.DataFun ctions.Money(Pa yment.payment_a mount)

results in the following text in the email:

Card Type: Visa
Credit Card Number: ?Hn<j;?AKPBROcT YPSiUjk Expiration Month: 7 Expiration Year: 2008 Payment Amount: $25.34

with Space characters where there should be CRLF characters. Changing the second line from
MT = MT & vbCrLf & "Credit Card Number: " & objBOWallet.Enc rypt(Payment.[_account_number])
to
MT = MT & vbCrLf & "Credit Card Number: " & Tab(1) & objBOWallet.Enc rypt(Payment.[_account_number])
(adding the Tab(1)) "fixes" the problem, but I can't see why. Why would a Tab character in one line impact the CRLF characters in three subsequent lines?

The most recent behavior is, to me, even more bizarre as I am now getting CRLF characters appearing in the middle of what are string literals in the code. For example, the following code

If Not IsNull(OrderFor m.advcode) Then
MT = MT & vbCrLf & "Affilate or Advertising code:" & Tab(1) & Trim(OrderForm. advcode)
End If
If Not IsNull(OrderFor m.Special_Offer ) Then
MT = MT & vbCrLf & "Special Offer Code:" & Tab(1) & Trim(OrderForm. Special_Offer)
End If
MT = MT & vbCrLf & "Order Number:" & Tab(1) & OrderForm.Order Number

results in the following text in the email:

Affilate or Advertising code:Special
Offer Code:Order
Number: 10100625021

Instead of getting CRLF characters before the "Special Offer Code:" and "Order Number:" strings, there are CRLF characters inserted into the middle of each string. I can't make head nor tails of what's going on. Has anyone seen anything like this???

Never mind. I had my VBScript right the text out to a file and found that it was correctly formatted. Somewhere in the mail processing (mail server, mail client, SMTP stack) it's getting messed up. Not sure there's much I can do about that.
