为什么带有cell.value的宏会停止工作，并给我返回错误2015？

Question

 Sub ProbationEmailGeneral()
Dim r As Range
Dim cell As Range


Set r = Range("CI:CI")


For Each cell In r

    If cell.Value = Date Then

        Dim Email_Subject, Email_Send_From, Email_Send_To, _
        Email_Cc, Email_Bcc, Email_Body As String
        Dim Mail_Object, Mail_Single As Variant

        Email_Subject = "TEXT"
        Email_Send_From = "email"
        Email_Send_To = "email"
        Email_Cc = ""
        Email_Bcc = ""
        Email_Body = "TEXT"

        On Error GoTo debugs
        Set Mail_Object = CreateObject("Outlook.Application")
        Set Mail_Single = Mail_Object.CreateItem(0)
        With Mail_Single
        .Subject = Email_Subject
        .To = Email_Send_To
        .cc = Email_Cc
        .BCC = Email_Bcc
        .Body = Email_Body
        .send
        End With

    End If

Next


Exit Sub

调试：         如果Err.Description <>“”然后MsgBox Err.Description

结束子

这是代码。昨天它可以正常工作，但是当我尝试启动它时，它给了我一个错误2015，并使此行“ If cell.Value = Date Then”变为黄色。
