Functions: Need some help getting vars to work when called

I have been given a function to use to generate a number. (Assume the function code is correct). When I pass my vars to it, it's not displaying the value. I believe I'm just using it wrong. Can anyone provide some assistance?  Thanks.

Code:

'Find if Consumer_ID in the database for Online Coupon routine
Dim intCID2
Dim cpnFNAME
Dim cpnLNAME
Dim strQuery2
Dim rsEmailFind2
Dim vString
Dim vKey
Dim vOffer
Dim encodeX
Dim eString

intCID2 = -1

set rsEmailFind2= Server.CreateObject("ADODB.Recordset")
strQuery2 = "SELECT Consumer.Consumer_ID, Consumer_FName, Consumer_LName FROM Consumer where Consumer.Consumer_Email = '"&Request.Form("Email")&"'"
rsEmailFind2.Open strQuery2, oConn

If Not rsEmailFind2.EOF Then
'get the consumer ID of the consumer for the Email Entered
intCID2 = rsEmailFind2("Consumer_ID")
cpnFNAME = rsEmailFind2("Consumer_FName")
cpnLNAME = rsEmailFind2("Consumer_LName")
End If
rsEmailFind2.Close
'Delete the Recordset Object
Set rsEmailFind2 = Nothing

' intCID2 now contains the PIN code for the coupons

vString = intCID2
vKey = "4gdbx8y0l6"
vOffer = "4096"
encodeX = "zkfAde37ncWxNQ8pM1VuiwG5gjvtKJSZURayFbClH6TL4IYE2OPhsqDo9rXBm"

' **********************************************************
' Coupon Function Routine (this is what I cannot get called correctly)
' **********************************************************

function EncodeCPT(vString,vKey,vOffer,encodeX)

'vString is the p code
'vKey is the Short key
'vOffer is the o code
'encodeX is the long Key

'init
decodeX = " abcdefghijklmnopqrstuvwxyz0123456789!$%()*+,-.@;<=>?[]^_{|}~"

dim vob(2)
dim encodeModulo(256)
vob(0) = int(vOffer/100)
vob(1) = vOffer mod 100
for i = 1 to 256
encodeModulo(i) = 0
next

for i = 0 to 60
encodeModulo(asc(mid(decodeX,i+1,1))) = i
next

'append offer code to key
vString = lcase(vString) & vOffer
if len(vString) < 20 then
vString = Left(vString & " couponsincproduction",20)
end if
'encode
i=0
q=0
j=len(vString)
k=len(vKey)
eString = ""
for i = 1 to j
s1 = encodeModulo(asc(mid(vString,i,1)))
s2 = 2 * encodeModulo(asc(mid(vKey,1+((i-1) mod k),1)))
s3 = vob(i mod 2)
q = (q + s1 + s2 + s3) mod 61
eString = eString & mid(encodeX,q+1,1)
next

EncodeCPT = eString
end function

Response.write "Fname: " &cpnFNAME & "<br>"
Response.write "Lname: " & cpnLNAME & "<br>"
Response.write "vString (ID): " & vString & "<br>"
Response.write "vOffer: " &vOffer & "<br>"
Response.write "encodeX: " & encodeX & "<br>"
Response.write "EncodeCPT: " & eString & "<br>"
Response.end

The webpage displays above return:

Yup, I got it:

Response.write "Function: " & EncodeCPT(vString,vKey,vOffer,encodeX) & "<br>"

Thanks!
