调用子例程的输出不正确

Question

我的程序旨在从 excel 工作表中输入 GPA、学生身份和学分，并使用它们来计算给定学生的学费、杂费、折扣和应付总金额。

我必须使用单独的子例程来解决工作表中每个人的学费、杂费、折扣和总额。

我的问题是，当我尝试对我的主要子例程调用不同的子例程并获得我需要的值时，它会显示一个随机数，并且不使用访问费用或其他子例程设置值的任何部分。

我尝试移动我的声明，但代码只是收到更多错误。

'Primary subroutine
Sub Proj_5p2()
'Variables
Dim dblGPA As Double
Dim strStat As String 
Dim intRow As Integer
Dim intCredHrs As Integer
Dim curTuition As Currency
Dim curFees As Currency
Dim curDisc As Currency
Dim curTotal As Currency
'Processing
Do While (Range("a" & intRow) <> "")
    'Get required input for each row
    dblGPA = Range("c" & intRow).Value
    strStat = UCase(Range("d" & intRow).Value)
    intCredHrs = Range("e" & intRow).Value
    'Call subroutines
    Call Tuition(curTuition, intCredHrs, strStat)
    'Display subroutines
    Range("f" & intRow) = curTuition
Loop
End sub
'Call from subroutine
Sub Tuition(curTuition As Currency, intCredHrs As Integer, strStat As String)
   If strStat = "GRADUATE" Then
        If intCredHrs < 18 Then
            curTuition = 335 * intCredHrs
        Else
            curTuition = 6500
    End If
    ElseIf strStat = "UNDERGRADUATE" Then
        curTuition = 550 * intCredHrs
    End If
End Sub

我需要它根据学生的学分和大学状态来计算学生的学费。

在我的代码中，我让它完成了 10 个学分的本科生。这应该导致 3,350.00 美元的学费，但结果只是 300.00 美元。

我不知道它从哪里得到 300。

很难说没有看到整个事情(数据+宏(，但我敢打赌，您的主子例程中没有工作簿或工作表声明。现在，它可以从其他工作表甚至打开的工作簿中读取。

我要补充一点：

    Sub Proj_5p2()
    ' Delcare your workbook and worksheet
    Dim wb as Workbook
    Dim ws as Worksheet
    ' If data in the same workbook as the macro,
    ' or a static name: Set wb = Workbooks("bookname.xlsx")
    Set wb = ThisWorkbook 
    Set ws = wb.Worksheets("nameofsheet")

    'Variables
    Dim dblGPA As Double
    Dim strStat As String 
    Dim intRow As Integer
    Dim intCredHrs As Integer
    Dim curTuition As Currency
    Dim curFees As Currency
    Dim curDisc As Currency
    Dim curTotal As Currency
    ' Adds the worksheet reference, now each range object with .Range
    With ws
    'Processing
    Do While (.Range("a" & intRow) <> "")
    'Get required input for each row
    dblGPA = .Range("c" & intRow).Value
    strStat = UCase(.Range("d" & intRow).Value)
    intCredHrs = .Range("e" & intRow).Value
    'Call subroutines
    Call Tuition(curTuition, intCredHrs, strStat)
    'Display subroutines
    .Range("f" & intRow) = curTuition
    Loop
    End With
