我的 VLookup 函数有问题，因为它找不到我知道在该范围内的值。Product 变量必须保留为字符串，因为我正在查找数字和混合数字与文本。我的导师也不允许使用变体。 

Sub LookupValue()
Dim Product As String
Dim ErrCheck As Boolean
Dim Quantity As Integer
Dim Discount As Double
Dim myRange As Range

Set myRange = Worksheets("Prices").Range("A2:C21")

ErrCheck = True

'Obtaining VLookup Value
Product = InputBox("Enter the product's code.")

'Error checking
Do Until ErrCheck = False
    If Product = "" Then
        ErrCheck = True
        MsgBox ("Not a valid entry.")
        Product = InputBox("Enter the product's code.")
    ElseIf IsError(Application.VLookup(Product, myRange, 3, False)) Then
        ErrCheck = True
        MsgBox ("The value entered was not found.")
        Product = InputBox("Enter the product's code.")
    Else
        ErrCheck = False
    End If
Loop

'Obtaining Quantity Value
Quantity = InputBox("Enter the quantity ordered.")

'Error checking
Do Until ErrCheck = False
    If IsNumeric(Quantity) = False Then
        ErrCheck = True
        MsgBox ("Not a valid entry.")
        Quantity = InputBox("Enter the quantity ordered.")
            Else
                ErrCheck = False
    End If
Loop

'Obtaining discount rate
If Quantity < 25 Then
    Discount = 0.1
    If Quantity < 50 Then
        Discount = 0.15
        If Quantity < 75 Then
            Discount = 0.2
            If Quantity < 100 Then
                Discount = 0.25
                If Quantity >= 100 Then
                    Discount = 0.3
                End If
            End If
        End If
    End If
End If

'Filling in cells
Sales.Range("B2") = Product
Sales.Range("B3") = Application.VLookup(Product, myRange, 2, False)
Sales.Range("B4") = Quantity
Sales.Range("B5") = Discount
Sales.Range("B6") = Application.VLookup(Product, myRange, 3, False)
Sales.Range("B7") = Range("B6").Value * Quantity
Sales.Range("B8") = Range("B7").Value * Discount
Sales.Range("B9") = Application.WorksheetFunction.Sum("B7:B8")

End Sub

您检查的数据是数字类型，但是，您向 VLOOKUP 函数提供了一个字符串。

因此，代替Application.VLookup(Product, myRange, 3, False), 使用

Application.VLookup(Val(Product), myRange, 3, False)
