Excel VBA range.find acting up

问题

Im trying to use range.find to look up a value within a column, and return the matching value from the next column.

I recorded the find() using the macro recorder, which seemed to work fine for a while, but for some reason it's now giving me an error. As far as I can tell I haven't changed anything that should affect this bit of code.

This is what I have

Public Function look_up_id(id, table)
    Worksheets(table).Activate
    Cells.Find(What:=id, After:=ActiveCell, LookIn:=xlFormulas, LookAt _
        :=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
        False, SearchFormat:=False).Activate

    look_up_id = ActiveCell.Offset(0, 1).Value
End Function

The error I'm now getting is:

Object variable or With block variable not set

Any idea why this is now happening?

All the resources I can find on range.find() look like I'm doing it right...

Cheers - David

Try this

Public Function look_up_id(id, table) As Variant
    Dim ws As Worksheet
    Dim aCell As Range

    look_up_id = "Not Found"

    Set ws = ThisWorkbook.Sheets(table)

    With ws
        Set aCell = .Cells.Find(What:=id, _
                    LookIn:=xlFormulas, _
                    LookAt:=xlPart, _
                    SearchOrder:=xlByRows, _
                    SearchDirection:=xlNext, _
                    MatchCase:=False, _
                    SearchFormat:=False)

        If Not aCell Is Nothing Then _
        look_up_id = aCell.Offset(, 1).Value
    End With
End Function

Try to use this code instead (when Find doesn't find anything, it returns Nothing and then you tried to do sth like this Nothing.Activate, and this triggers an error):

Dim res As Range

Set res = Worksheets(table).Cells.Find(What:=id, LookIn:=xlFormulas, LookAt _
    :=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
    False, SearchFormat:=False)
If Not res Is Nothing Then
    look_up_id = res.Offset(0, 1).Value
End If
