Instantiating VBA financial functions through VBScript

I need to access PMT and RATE functions found within the VBA library through an ASP page.
I don't want to really wrap this function within a COM object and reference that way. I was hoping to be able to access these functions through VBScript via a valid PROGID.
The server on which this will reside will not have MS Office installed on it.
The backend is SQL Server 7 with no OLAP services installed [unable to use a stored procedure to compute rate or pmt]

Does anyone have any ideas?
Thanks

you could write them into a DLL file and call it in the ASP page.

I was wondering if I could directly access these functions via VBScript without using a DLL
EG:
<%

Dim objA
Dim dblPMT
Set objA = server.createobject("?")
dblPMT = objA.PMT(....)

%>
THe problem is working out the PROGID [i.e. "?"]

sorry asbailey, but I don't think it is possible.  Here's what I have found...

CreateObject Function
Creates and returns a reference to an Automation object.

CreateObject(servername.typename [, location])

Arguments
servername

Required. The name of the application providing the object.

typename

Required.The type or class of the object to create.

location

Optional. The name of the network server where the object is to be created.

It looks like VBA objects don't support IDispatch interface that allows Automation....rats man

by the way...

Why the grade of "C"?

you asked: "I was hoping to be able to access these functions through VBScript via a valid PROGID. "

i told you it's not possible unless you create a DLL, you said: "I was wondering if I could directly access these functions via VBScript without using a DLL"

again i said, it's not possible.

i find no logic in a "C" grade...
