if error msg then

[deb]

I have a form that enters schedule images.

If user tries to enter a duplicate, I would like to display a warning msg
and give options to proceed.

How should this be written?

if error 3022- The changes you requested to the table were not successful
because they would create duplicate values in the index, primary key, or
relationship. Change the data in the field or fields that contain duplicate
data, remove the index, or redefine the index.

Then...

Msg = "Warning Schedule Image for selected Report Date and Page was
previously entered." _
& vbCr & vbCr & "Yes, to be directed to the original record." _
& vbCr & "No, to delete current record." _
& vbCr & "Cancel, to make changes to current record."
ans = MsgBox(Msg, vbYesNoCancel)

If ans = vbNo Then
Me.Undo
DoCmd.DoMenuItem acFormBar, acEditMenu, 8, , acMenuVer70
DoCmd.DoMenuItem acFormBar, acEditMenu, 6, , acMenuVer70
DoCmd.GoToRecord , , acNewRec
MsgBox "Duplicate Deleted."
Exit Sub

ElseIf ans = vbYes Then
Me.Undo
'Go to record of original ID
rsc.FindFirst stLinkCriteria
Me.Bookmark = rsc.Bookmark
Exit Sub
End If

Thanks in advance,

You need Error Handlers. They trap errors and take action that you
code. Within the Error Handler for a given procedure you can use a
Select -- Case statement to fine tune responses to some specific
errors while letting all others fall through to your default response.

There are some 3rd party tools that can help you along with the
process. MZTools is the first that comes to mind. It's a free
download and it's very powerful. There *should be* an Error Handler
in every procedure.
