I am using DAO or the data control for working with the database. I have two text boxes – txtItemNumber and txtDescription and a command button – cmdFind on my form. And, I was trying to search for a part item number, but I got the run-time error – it says that ‘3077’: Syntax error (missing operator) in expression. Please help me...Thank you.
The user enters a Item Number and clicks on the Fund button to get the Item Number’s record.
Dim db As Database
Dim rs As Recordset
Dim num1 As Integer
Dim target As String
Private Sub cmdFind_Click()
Data1.DatabaseName = App.Path & "\Ampem.mdb"
Data1.RecordSource = "Select * FROM Inventory"
num1 = txtItemNumber.Text
if num1 = “” then
exit sub
else
target = "Item Number = '" & num1
Data1.Recordset.FindFirst target
If Data1.Recordset.NoMatch Then
MsgBox "no found"
Exit Sub
Else
MsgBox "found"
txtItemNumber.Text = num1
Exit Sub
End If
End if
End Sub

You have a Table Name which Includes Spaces this is what's causing the secific error you're getting, you need to enclose the Table Name in Square Braces, eg.
target = "[Item Number] = '" & num1
You're also missing the Enclosing Apostrophe on the same line, it should be..
target = "[Item Number] = '" & num1 & "'"

It is a lot easier to use DAO:
Code:
Dim db As Database
Dim rs As Recordset
Dim num1 As Integer
Set db = Workspaces(0).OpenDatabase(App.Path & "\Ampem.mdb")
num1 = Val(txtItemNumber.Text)
If num1 = 0 Then ' "" Then
Exit Sub
End If
Set rs = db.OpenRecordset("Select * FROM Inventory Where [Item Number] ='" & num1 & "'", dbOpenSnapshot)
If rs.EOF Then
MsgBox "Item NOT Found."
Else
MsgBox "Item Found."
End If

It runs perfectly! Thanks, Aaron!!! I really appreciate that! Again, thank you.

Aaron and Serge, thank you all very much for helping me on this problem. But, I have a several questions. I now am using DAO and Access MDB for working with the database. Before that, I used a flat file ( Random Access File) and the data control to work with the database. Which one is more easier to use? DAO, the Data Control, ADO, or a flat file?
As I said earlier, I have two text boxes and a command button (cmdAdd for now) on my form. When I click on the Add button, I enter a item number for an existing item number. A message box should display informing me that the item number already exists. But, I got the run-time error “Data Type mistake in criteria expression” I just want to test if there is an existing item number or not. If found, it cancels everything what I type (not adding data to the database when I unload the form) Do you know what I mean? If you don’t know what I mean, please let me know and I will rephrase for you all. Please help… Thank you.

Just jumping in here...
Did you change your field "Item Number" to be "ItemNumber"? In your first example it has a space. In the next, it doesn't. This may be the source of your problem(?).
-
Yes, I changed my field "Item Number" to
"ItemNumber" Please help with my current code. Thank you...
-
The Value you are searching on is Numeric, (Integer), yet you are enclosing it in Apostrophes, indicating it's a String, giving you the Error, change..
inum1 = Val(txtItemNumber.Text)
target = "[ItemNumber] = '" & inum1 & "'"
To..
inum1 = Val(txtItemNumber.Text)
target = "ItemNumber = " & inum1
