Why isn't MS Access "item found in collection?" - ms-access

Question

I have a non-linked table "tblGrantRptData" in which I am trying to modify field records for subsequent filtering and export to EXCEL. I have ensured that all field names are correctly spelled, yet I still get an Error 3265, Item not found in this collection.
I have confirmed that MemmonthlyIncome is the correct spelling and is identified in the design as "currency."
here is the design veiw that appears to show the field name:
It stops at this line:
If IsNull (!MemmonthlyIncome) Then
with the error 3265
If I can get some help to resolve this, I would then like to store the range "0-30"....
One suggestion below was to “decompile" and "recompile.” I have read that this may cause problems when the database is used on multiple workstations. I have revised the code to just get to first base….Any suggestions?
Private Sub cmdGenerateGrantRpt_Click()
'now run the qqAll query - this generates the tblGrantRptData - then close the query
DoCmd.SetWarnings False
DoCmd.OpenQuery "qqAll", acViewNormal, acEdit
DoCmd.Close acQuery, "qqAll"
DoCmd.SetWarnings True
'First set up the table: tblGrantRptData with the correct data in fields
Dim db As DAO.Database
Dim rs As DAO.Recordset
Set db = CurrentDb
Set rs = db.OpenRecordset("tblGrantRptData", dbOpenTable)
'Check to see if the recordset actually contains rows and fill in particular values
With rs
If .EOF And .BOF Then
MsgBox "There are no records in this time interval"
Exit Sub
Else
.MoveFirst
Do Until .EOF = True
'Replace the monthly income with income categories
If IsNull(!MemmonthlyIncome) Then
.Edit
!MemmonthlyIncome = "0-30"
.Update
End If
Loop
End If
End With
rs.Close 'Close the recordset
Set rs = Nothing 'Clean up
End Sub

Answer 1

You get error #3265, "Item not found in this collection", at IsNull(!MemmonthlyIncome) in this context ...
Set rs = db.OpenRecordset("tblGrantRptData", dbOpenTable)
With rs
If IsNull(!MemmonthlyIncome) Then
That would happen if tblGrantRptData does not include a field named MemmonthlyIncome. What you are seeing as the column heading in the table Datasheet View may be the field's Caption property. You could check the field's Name and Caption properties in the table's Design View. Or you could list the actual field names for your table in the Immediate window.
Here's an abbreviated list of the field names in my Contacts table:
set db = currentdb
for each fld in db.TableDefs("Contacts").Fields : ? fld.name : next
ID
Company
Last Name
First Name
You just added this screen capture of your table in Design View ...
Notice the field is named MemmothlyIncome, not MemmonthlyIncome (moth vs. month). So it wasn't a Name vs. Caption difference after all; you simply tried to use a misspelled field name. That spelling problem is also visible in the DataSheet View screen capture, but we didn't notice it there.

Answer 2

In VBA, there is no Is Null expression as there is in SQL. Change to IsNull(rs!MemmonthlyIncome).
Possibly, Null is being referenced in recordset collection and hence returning the error.
