How to get a VBA code to find a subform

I have an Access db with an Invoice form that also had a detail subform. The Invoice is an order form and the detail subform lists: quantity, description item ordered, and the inventory in stock for that item. I have a cmd button that activates a module that is to update the inventory. It is to find the description item ordered in the inventory table and subtract the quantity ordered from the stock. I cannot get the code to find the subform no matter how I type it. How do you code VBA in order to find fields in a subform?

try the following:

me.frmSub.form!fieldX

where frmSub is name of your subform, fieldX name of field

my code assumes you are trying to reference the subform from your main form.

me.frmSub.form!fieldX

if your name of your subform or field has spaces then you would have to enclose them in [ ] square brackets as ravl stated.

I'd use code like this:

private sub test()
dim rs as dao.recordset
dim fld as dao.field

set rs = forms("InvoiceFormName").Controls("SubformControlName").Form.Recordset
do while not rs.eof
for each fld in rs.fields
debug.print fld.name & ":" & fld.value
next fld
rs.move.next
loop
set fld=nothing
rs.close
set rs=nothing
end sub

Here is my code. It works properly except it will not move to the next record in the subform. Can you make suggestions to help me complete this task?

Public Function UpdateInventory()

'declare variables and assign address to object variables

Dim cnnMSF As ADODB.Connection
Set cnnMSF = Application.CurrentProject.Connection

Dim Description As String, Quantity As Long, Stock As Long
Dim rstInventory As ADODB.Recordset, Invoice As Form

Set rstInventory = New ADODB.Recordset
Set rstInvoiceDetails = New ADODB.Recordset
Set Invoice = Application.Forms("Invoice")

'open recordset Inventory & InvoiceDetails, Invoice should be open already
rstInventory.Open Source:="Inventory", ActiveConnection:=cnnMSF, _
CursorType:=adOpenForwardOnly, LockType:=adLockPessimistic
rstInvoiceDetails.Open Source:="InvoiceDetails", ActiveConnection:=cnnMSF, _
CursorType:=adOpenForwardOnly, LockType:=adLockPessimistic

'assign values to controls on the form
Description = Forms![Invoice].[InvoiceDetails]![Description]
Quantity = Forms![Invoice].[InvoiceDetails]![Quantity]
Stock = Forms![Invoice].[InvoiceDetails]![Stock]

'search for the Description in Description field
rstInventory.Find criteria:="Description = '" & Description & "'"

'calculate Stock remaining after invoice purchase
Do Until rstInvoiceDetails.EOF
If Stock >= Quantity Then
rstInventory.Fields("Stock").Value = Stock - Quantity
End If
'move record pointer to the next record
rstInvoiceDetails.MoveNext
Loop

'save changes to record
rstInventory.Update

'close the recordset
rstInventory.Close
Set rstInventory = Nothing 'disassociate object variable from object

'close the recordset
rstInvoiceDetails.Close
Set rstInvoiceDetails = Nothing 'disassociate object variable from object

End Function
