我的VB.net语法错误怎么回事？

Question

Form1.stockCommand.Connection = requestConnection
    Form1.stockCommand.CommandText = "Insert into UserOrders(TickerSymbol,DateTime,OrderType,StockQuantity,OrderStatus) Values('" &
        Form1.StockComboBox.Text & "','" & Date.Today & "','" & Form1.TradeTypeComboBox.Text & "','" & Form1.QuantityTextBox.Text & "','PENDING')"

    Dim numOfRecords As Integer = Form1.stockCommand.ExecuteNonQuery()
    If numOfRecords = 1 Then
        MsgBox("A new order has been added successfully")
    Else
        MsgBox("Failed to add a new order")
    End If

更具体地说，VB.NET说＆＃34;未处理的类型＆＃39; System.Data.OleDb.OleDbException＆＃39;发生在System.Data.dll

中

附加信息：INSERT INTO语句中的语法错误。＆＃34;

我的所有访问名称都对应于代码中的名称。

谢谢！
