Get item in VBA Collection by Name - vba

Question

Ahoy hoy,
I'm trying to do stuff to a custom object in a custom collection by referencing it's name property in VBA Excel. I swear it worked before (or at least didn't throw an error) and now its kaput. I'm getting an invalid call or argument error when I try to Get something by a string. Thanks in advance for even reading this too, any help is appreciated. <\edit>
Here's the collection:
Option Explicit
Private DRAFields As New Collection
Sub Add(Name As String, Optional colNbr As Long, Optional Exists As Boolean)
Dim fld As New DRAFld
fld.colNbr = colNbr
fld.Name = Name
fld.Exists = Exists
DRAFields.Add fld
End Sub
Property Get Item(NameOrNumber As Variant)
Set Item = DRAFields(NameOrNumber) '<------- Error here
End Property
The collections has items added by passing an array of names in to a function and the collection is returned without issue. I can iterate over by using the key. But the error happens if get as such: Debug.Print myFlds.Item("Customer").colNbr
And the object class just in case:
Option Explicit
Private clmNbrPvt As Long
Private namePvt As String
Private existsPvt As Boolean
Public Property Get colNbr() As Long
colNbr = clmNbrPvt
End Property
Public Property Let colNbr(lngParam As Long)
clmNbrPvt = lngParam
End Property
Public Property Get Name() As String
Name = namePvt
End Property
Public Property Let Name(strParam As String)
namePvt = strParam
End Property
Public Property Get Exists() As Boolean
Exists = existsPvt
End Property
Public Property Let Exists(booParam As Boolean)
existsPvt = booParam
End Property
And why not that function too:
Function validateAndBuildDRAFields(ByRef arrReqFields() As String, _
inputSheet As Worksheet, _
Optional VBAModule As String) As clsDRAFields
Dim lEndCol As Long: lEndCol = Standard.zGetLastColumn(inputSheet, 1)
Dim i As Long
Dim x As Long
Dim intExit As Long
Dim myDRAFields As New clsDRAFields
Set validateAndBuildDRAFields = myDRAFields
'Builds myDRAFields items from arrReqFields
For i = LBound(arrReqFields) To UBound(arrReqFields)
myDRAFields.Add arrReqFields(i)
Next i
'checks if required fields exist on input sheet
'if found then sets column number and exists = true
For i = 1 To myDRAFields.Count
For x = 1 To lEndCol
If inputSheet.Cells(1, x) = myDRAFields.Item(i).Name Then
myDRAFields.Item(i).colNbr = x
myDRAFields.Item(i).Exists = True
intExit = intExit + 1
Exit For
End If
Next x
If intExit = UBound(arrReqFields) + 1 Then Exit For
Next i
' tells user if there are any missing fields and ends if true
If (Not intExit = UBound(arrReqFields) + 1) Or _
intExit = 0 Then
For i = 1 To myDRAFields.Count
If myDRAFields.Item(i).Exists = False Then
Call Standard.TheEndWithError("I couldn't find the " & myDRAFields.Item(i).Name & _
" column in your file. Please add " & myDRAFields.Item(i).Name & _
" to your DRA Layout.", False, VBAModule)
End If
Next i
Set myDRAFields = Nothing
Standard.TheEnd
End If
End Function

To access a collection item by its key, you have to supply a key when you add the item to the collection. The key is optional. When you access a collection item with a string, the Item method assumes you want to match the key. When you use an integer, it assumes you want the positional index.
So, change the line in your Add method to
DRAFields.Add fld, fld.Name
and you'll be able to access items by their Name property.
