How to insert a default parameter value in VB OR use another function in report query

P: 1

I searched online for some similar issues that I am facing but was not able come up with anything. I am fairly new with Access (2 months experience) and I am trying to remove a message stating, ENTER PARAMETER VALUE when I am generating a report. I know that the culprit lies in the query stored in the report. I have entered data in the CRITERIA (entered forms!frmproducts!lngproductID) window and OR (entered forms!frmproduser!lngproductID) window. The problem is that if one is filled with a value, the other one asks for a value through an ENTER PARAMETER VALUE window.

I would like to avoid using two reports (one for each form) to solve the problem by only have one criteria filled in each report query.

There are two ways I could think of to solve the problem:

First way: using VB to detect and automatically fill in a value of '0' (zero) when the form frmproducts is closed on the same computer.

I have two forms that print to the exact same report:
1) forms!frmproducts!lngproductID - for administrator
2) forms!frmproduser!lngproductID - for product manager (limited data changes and access).

Below is the current VB code from print command button on the form, FRMPRODUSER.

*** BEGIN VB CODE *****
Expand|Select|Wrap|Line Numbers
  1. Private Sub Preview_Click()
  2. On Error GoTo Err_Preview_Click
  3.     DoCmd.DoMenuItem acFormBar, acRecordsMenu, acSaveRecord, , acMenuVer70
  4.     If IsNull(Me![LngProductID]) Then
  5.         MsgBox "Please enter the product data in the form."
  6.     Else
  7.         MsgBox "Opening default label, 4x3, to preview for printing."
  8.         DoCmd.OpenReport "rpt4x3StdLabel", acPreview, , "Forms![frmProdUser].[lngProductID]=" & Me![lngProductID]
  9.     End If
  11. Exit_Preview_Click:
  12.     Exit Sub
  14. Err_Preview_Click:
  15.     If Err <> 2501 Then
  16.         MsgBox Err.DESCRIPTION
  17.     End If
  18.     Resume Exit_Preview_Click
  19. End Sub
*** END VB CODE ***

Secondly, is there a function that would be satisfied if only one form forwards the data via VB? I would be entering the parameters in teh CRITERIA box in the report query.

I hope that I am making sense. If not, feel free to clarify. I am self-taught on Access (by way of books and reading online), so I am not quite familiar with the common terms you all use.

Any help would be greatly appreciated.

This is probably easier than you think.
But, to guide you through it I'll need the SQL of the query your report uses.
I think it's a great idea to use the same report flexibly - I try to do that all the time myself.
Your stLinkCriteria is definitely wrong!
What it should be I can only tell with access to the reports query SQL.
In outline, though, it should say something like :
Expand|Select|Wrap|Line Numbers
  1. "([ProductID]=" & Me.[lngProductID] & ")"
Assuming the query has a field being filtered called [ProductID].
Assuming also (from name lngProductID) that field is numeric.

I'm not sure what your second question was about.
If it still needs an answer then ask me again (perhaps using different wording).
