Vba 尝试在access窗体上使用Controls（）函数时出错

我正试图从access中的几个表单控件值构建一个SQL insert语句

我已经读到可以使用Controls（）函数动态引用我的控件

我尝试过这样做：

   Private Sub InsertCoeff(ByVal prov As String, ByVal region As String)
    Dim strSQL As String
    Dim insertSQL As String
    Dim valuesSQL As String
    insertSQL = "INSERT INTO 'Coefficient de Fermage'"
    valuesSQL = "("
    valuesSQL = valuesSQL & "('1F','2F')"
    valuesSQL = valuesSQL & ",('" & Me.Controls(prov & region & "Lbl") & "','" & Me.Controls(prov & region & "Lbl") & "')"
    valuesSQL = valuesSQL & ",('" & Me.Controls(prov & "Lbl") & "','" & Me.Controls(prov & "Lbl") & "')"
    valuesSQL = valuesSQL & ",('" & Me.Controls(prov & region & "Terres") & "','" & Me.Controls(prov & "Bat") & "')"
    valuesSQL = valuesSQL & ",('" & Me.DateEff & "','" & Me.DateEff & "')"
    valuesSQL = valuesSQL & ")"
    strSQL = insertSQL & " VALUES " & valuesSQL
End Sub

但我得到一个运行时错误438（对象不支持此属性或方法），即使在我开始键入“Me”时vba自动建议Controls（）方法

知道为什么会失败吗？

我在引用标签，所以正确的语法是

valuesSQL = valuesSQL & ",('" & Me.Controls(prov & region & "Lbl").Caption & "','" & Me.Controls(prov & region & "Lbl").Caption & "')"
