asp.net - 编译器错误消息：BC30451：未声明名称“cmbY”

Question

我在此代码中收到非声明错误。

    Line 23:         If Not Page.IsPostBack Then
    Line 24: cmbY.DataSource = rsFirehose("SELECT LeagueTypeKey, LeagueTypeDescription FROM LeagueType " & _**
    Line 25:                 "WHERE LeagueTypeKey=0 or (Appkey=" & glngAppKey & " AND LeagueTypeKey IN (SELECT Distinct YKey FROM " & _
    Line 26:                 "Division WHERE DivisionTypeKey=" & soaDivisionTypeBracket & ")) ORDER BY LeagueTypeDescription")

第 24 行是错误所在：它表示未声明名称“cmbY”。我该如何申报？
