MS Access ADO open question

I have the following code in an Access 2007 DB.  When I get to the line that is supposed to open rstIW I get an error that states:
Run time error 91
Object variable or With Block variable not set.

I tried creating a second connection called cnnLocal2 but that didn't work, I got the same error.
It's probably a rookie mistake (because I am one) but I can't see it.  What am I doing wrong?

Sub Extract_Raw_Data()
    Dim cnnLocal As New ADODB.Connection
    Dim rstExcel As New ADODB.Recordset
    Dim rstIW As ADODB.Recordset
    Dim IWType As String
    Dim IWSubType As String
    Set cnnLocal = CurrentProject.Connection
    rstExcel.Open "Select * from ImageWires", cnnLocal, adOpenStatic, adLockPessimistic
    rstIW.Open "Select * from tblIW WHERE 1 = 0", cnnLocal, adOpenDynamic, adLockOptimistic
   
    While Not rstExcel.EOF
        If rstExcel.Fields("F2") = "Pre-Labeled ImageWires 1.5" Or _
           rstExcel.Fields("F2") = "Pre-Labeled ImageWires 1.8" Or _
           rstExcel.Fields("F2") = "Pre-Labeled C7 Dragonfly" Then
            IWType = rstExcel.Fields("F2")
        End If
        If (rstExcel.Fields("F2") = "12424-00" Or _
           rstExcel.Fields("F2") = "12513-00" Or _
           rstExcel.Fields("F2") = "13751-00") And _
           rstExcel.Fields("F4") > " " Then   'Use the part # to indicate data rec and Lot # to show data present
            rstIW.AddNew
            rstIW.Fields("IW PN") = rstExcel.Fields("F2")
            rstIW.Fields("IW Lot") = rstExcel.Fields("F4")
            rstIW.Fields("IW Qty") = rstExcel.Fields("F6")
            If IsNumeric(rstExcel.Fields("F8")) Then
                rstIW.Fields("IW Exp_Date") = rstExcel.Fields("F8")
                rstIW.Fields("IW Status") = Null
            Else
                rstIW.Fields("IW Exp_Date") = Null
                rstIW.Fields("IW Status") = rstExcel.Fields("F8")
            End If
            rstIW.Fields("IW Type") = IWType
            rstIW.Update
        End If
       
        rstExcel.MoveNext
    Wend
    rstExcel.Close
End Sub

I think the problem in:

IWType = rstExcel.Fields("F2")

You set the "IWType" in the first IF statement but you do not if this condition has not been achieved. So in line 32 (rstIW.Fields("IW Type") = IWType) the "IWType" generate the error. You need to set "IWType" before the second "IF".
Also I think nesting the first "IF" with the other "IF"s will be better.


Sub Extract_Raw_Data()
    Dim cnnLocal As New ADODB.Connection
    Dim rstExcel As New ADODB.Recordset
    Dim rstIW As ADODB.Recordset
    Dim IWType As String
    Dim IWSubType As String
    Set cnnLocal = CurrentProject.Connection
    rstExcel.Open "Select * from ImageWires", cnnLocal, adOpenStatic, adLockPessimistic
    rstIW.Open "Select * from tblIW WHERE 1 = 0", cnnLocal, adOpenDynamic, adLockOptimistic
    
    While Not rstExcel.EOF
        If rstExcel.Fields("F2") = "Pre-Labeled ImageWires 1.5" Or _
           rstExcel.Fields("F2") = "Pre-Labeled ImageWires 1.8" Or _
           rstExcel.Fields("F2") = "Pre-Labeled C7 Dragonfly" Then
            IWType = rstExcel.Fields("F2")
        else
			IWType = ' =============================You need to set IWType here======================
			If (rstExcel.Fields("F2") = "12424-00" Or _
				rstExcel.Fields("F2") = "12513-00" Or _
				rstExcel.Fields("F2") = "13751-00") And _
				rstExcel.Fields("F4") > " " Then   'Use the part # to indicate data rec and Lot # to show data present
				rstIW.AddNew
				rstIW.Fields("IW PN") = rstExcel.Fields("F2")
				rstIW.Fields("IW Lot") = rstExcel.Fields("F4")
				rstIW.Fields("IW Qty") = rstExcel.Fields("F6")
				If IsNumeric(rstExcel.Fields("F8")) Then
					rstIW.Fields("IW Exp_Date") = rstExcel.Fields("F8")
					rstIW.Fields("IW Status") = Null
				Else
					rstIW.Fields("IW Exp_Date") = Null
					rstIW.Fields("IW Status") = rstExcel.Fields("F8")
				End If
				rstIW.Fields("IW Type") = IWType
				rstIW.Update
			End If
        End If
        rstExcel.MoveNext
    Wend
    rstExcel.Close
End Sub

Thank you for the response.  Actually I thought this note didn't go in.  I figured it out shortly after I finished typing it.  It was that I did not dim rstIW as a NEW ADODB.Recordset.  Once I put the New in there the code worked fine.

Regarduing the specific code.  The 1st If is a standalone.  The value only occurs on the first record (I'm reading an Excel Workbook that the inventory manager uses to manage consumables in our company).  Because the title (value) only occurs on the first record the IF has to be standalone as it will not be true on the 2nd - nth records.  I'm simply setting a temp value with the title of the data I'm about to read.

Thank you again.
