Question

我只是在学习使用VBA，并且通过用户窗体输入为计算创建了以下代码：

我的困难是确保VarCost，SemiVarCost和Desired Margin的计算是可选的。

也就是说，如果用户在userform文本字段中输入特定值，则会进行计算。如果不是，则该过程应将其计为0或null。
对于期望的保证金，如果用户输入了OKMargin = DesiredMargin，则为DesiredMargin。

有人可以帮我吗？

Private Sub Calculate_Click()
    Dim PIS, Cofins, ISS, Simples, LR, IRRJ, OKMargin As Double
    Dim GCom, eLComNet, ClientCom As Double
    Dim LucroReal, SimplesN, TaxationType As String
    Dim OptimalCommission As Currency
    Dim VarCost, SemiVarCost, DesiredMargin As Currency
    Dim ClientSpent As Currency

    'Ref the userform
    TaxationType = UserForm1.ComboBox1.Text
    SemiVarCost = UserForm1.SemiVarCost.Value
    VarCost = UserForm1.VarCost.Value
    ClientSpent = UserForm1.ClientSpent.Value
    DesiredMargin = UserForm1.DesiredMargin.Value

    ' Tax assumptions behind the calculations
    PIS = 0.0165
    Cofins = 0.076
    ISS = 0.05
    IRRJ = 0.34
    Simples = 0.062
    LR = PIS + Cofins + ISS + IRRJ
    GCom = 0.12
    OKMargin = 0.55

    'define taxation conditions
    If (TaxationType = "SimplesN") And (IsMissing(DesiredMargin)) Then
        eLComNet = (ClientSpent * GCom) - (ClientSpent * GCom * Simples)
        OptimalCommission = eLComNet - (eLComNet * OKMargin) - VarCost - SemiVarCost
    End If
    If (TaxationType = "LucroReal") And (IsMissing(DesiredMargin)) Then
        eLComNet = (ClientSpent * GCom) - (ClientSpent * GCom * LR)
        OptimalCommission = eLComNet - (eLComNet * OKMargin) - VarCost - SemiVarCost
    End If
    If (TaxationType = "SimplesN") And (Not IsMissing(DesiredMargin)) Then
        eLComNet = (ClientSpent * GCom) - (ClientSpent * GCom * Simples)
        OptimalCommission = eLComNet - (eLComNet * DesiredMargin) - VarCost - SemiVarCost
    End If
    If (TaxationType = "LucroReal") And (Not IsMissing(DesiredMargin)) Then
        eLComNet = (ClientSpent * GCom) - (ClientSpent * GCom * LR)
        OptimalCommission = eLComNet - (eLComNet * DesiredMargin) - VarCost - SemiVarCost
    End if

        UserForm1.OptCom.Value = OptimalCommission

End Sub

无法在用户窗体中创建可选字段
