Your passing a string to FindNext as an argument and you should be passing a
range reference is one possible cause.

What causes Run-time Error '1004' Unable to get the FindNext property of
the Range class

The code that causes it is:
Dim vrtSheetName As Variant
Dim vrtJobValue, vrtCustomerLocation As Variant
Dim vrtCustomerName, vrtValidationValue As Variant
Dim vrtOriginalLocation, vrtFirstAddress As Variant
Dim vrtValidationValueOld As Variant
Dim Msg, ans As Variant

vrtSheetName = ActiveSheet.Name

If ActiveCell.Row = 6 Then

With Worksheets("Customers & Jobs")

If Cells(7, ActiveCell.Column).Value = "Extra" Then

If ActiveCell.Value = "" Then Exit Sub

vrtCustomerName = Worksheets(vrtSheetName).Cells(6,
ActiveCell.Column - 1).Value

Worksheets("Customers & Jobs").Visible = True

Set vrtCustomerLocation =
Range("Customers").Find(What:=vrtCustomerName, LookIn:=xlValues)
vrtJobValue =
..Cells(Range(vrtCustomerLocation.Address).Row, 5).Value
vrtValidationValue = vrtJobValue
vrtOriginalLocation = vrtCustomerLocation.Address

Do

vrtCustomerLocation =
Range("Customers").FindNext(vrtOriginalLocation)
vrtJobValue = Empty
Set vrtJobValue =
..Cells(Range(vrtCustomerLocation).Row, 5).Value

If Not vrtJobValue = Empty Then
vrtValidationValueOld = vrtValidationValue
vrtValidationValue = vrtValidationValueOld
& "," & vrtJobValue
End If

Loop While vrtCustomerLocation < vrtFirstAddress
And Not vrtJobValue = Empty

With
Worksheets(vrtSheetName).Range(ActiveCell.Address)

.Validation.Delete
.Validation.Add Type:=xlValidateList,
AlertStyle:=xlValidAlertStop, Operator:=xlBetween,
Formula1:=vrtValidationValue

End With

Worksheets("Customers & Jobs").Visible = False
Application.ScreenUpdating = True
End If
End With
End If
