Error returned while using Index and Match formula - excel

Question

I am trying to use Index and Match to lookup a value on another worksheet within the same workbook, but I keep getting an error returned. (error 2042) I know I can do this using a formula, (see pic) but I'd like to use code. Does anyone mind taking a look?
Dim WorkOrderDashboardCell As Range
Dim ProjectList As Worksheet
Dim ProjectNumber As String
Set ProjectList = Worksheets("Project List")
ProjectList.Activate
'We need to start by initializing values on the project list
With ProjectList
Dim LastRowProjectListSpreadsheet As Long
LastRowProjectListSpreadsheet = .Range("B" & Rows.Count).End(xlUp).Row
Dim ProjectListNumbers As Range
Set ProjectListNumbers = .Range("B2:B" & LastRowProjectListSpreadsheet)
Dim ProjectListProjectNumber As Integer
ProjectListProjectNumber = 2
End With
'Switch back to the Dashboard spreadsheet
DashBoard.Activate
Dim DashboardWorkOrderRange As Range
Set DashboardWorkOrderRange = DashBoard.Range("E17:E" & LastRowProjectListSpreadsheet)
For Each WorkOrderDashboardCell In Range("E17:E" & Rows.Count).End(xlUp).Row
ProjectNumber = Application.Index(ProjectListNumbers, Application.Match(WorkOrderDashboardCell, DashboardWorkOrderRange, 0))
Debug.Print ProjectNumber
Next

Answer 1

To use worksheet functions, use code like:
WorksheetFunction.Index
rather than:
Application.Index
You might also need to use the Address property of your ranges, like:
ProjectListNumbers.Address

Answer 2

I think this line here is incorrect:
For Each WorkOrderDashboardCell In Range("E17:E" & Rows.Count).End(xlUp).Row
You are trying to loop within a range, but this part of the aforementioned line returns a row number not a range of cells:
Range("E17:E" & Rows.Count).End(xlUp).Row
Change it to a range of cells.

Answer 3

Application.Match
In your code you are using
Set DashboardWorkOrderRange = DashBoard.Range("E17:E" & LastRowProjectListSpreadsheet) where LastRowProjectListSpreadsheet is possibly the wrong last row. Also you are using
For Each WorkOrderDashboardCell In Range("E17:E" & Rows.Count).End(xlUp).Row where Range("E17:E" & Rows.Count).End(xlUp).Row is a row (instead of a range). Finally you are using Application.Filter without testing the result of Application.Match. Some other issues are the unnecessary use of Activate and the use of long variable names the latter seriously affecting the readability of the code.
This is your code revised. When running it you will see that it makes little sense (mentioned in the comments).
I'm posting it for you only to maybe easier find out what you really want to do.
It is illustrating how the result of Application.Match should always be tested with IsNumeric (or IsError) and that you don't have to (in this case, should not) use Application.Index, but just the Cells property of the range object with the index returned by Application.Match, to return the desired value.
The Code
Option Explicit
Sub LittleSense()
Dim wb As Workbook: Set wb = ThisWorkbook ' Workbook containing this code.
Dim LastRow As Long
Dim plRng As Range
With wb.Worksheets("Project List")
LastRow = .Range("B" & .Rows.Count).End(xlUp).Row
Set plRng = .Range("B2:B" & LastRow)
End With
Dim dbRng As Range
With wb.Worksheet("Dashboard")
LastRow = .Range("E" & .Rows.Count).End(xlUp).Row
dbRng = .Range("E17:E" & LastRow)
End With
Dim cel As Range
Dim dbIndex As Variant
Dim plValue As Variant
For Each cel In dbRng.Cells
dbIndex = Application.Match(cel, dbRng, 0)
' You might as well do:
'dbIndex = dbIndex + 1
If IsNumeric(dbIndex) Then ' Not necessary: all values will be found.
plValue = plRng.Cells(dbIndex).Value
Debug.Print plValue & " (" & dbIndex & ")"
Else
' Not necessary: all values will be found.
Debug.Print "Not found " & "(""" & cel.Value & """)"
End If
Next cel
End Sub
