好吧，我已经根据之前提出的问题，改变了我的代码三四次，仍然无法获得我正在努力将数据插入到我的表中的表单。寻找有用的建议。
表格代码：
<div>
<table align="center" width="200px" cellpadding="5px">
<tr><td width="50px">Season:</td><td width="150px">
<asp:DropDownList name="Season" ID="ddlSeason" runat="server" AutoPostBack="True" DataSourceID="SqlDataSource1" DataTextField="Season" DataValueField="Season">
</asp:DropDownList>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:SeasonConnectionString %>" ProviderName="<%$ ConnectionStrings:SeasonConnectionString.ProviderName %>" SelectCommand="SELECT * FROM [T_Season] ORDER BY [Season]"></asp:SqlDataSource>
</td></tr>
<tr><td>Game: </td><td>
<asp:DropDownList name="Game" ID="ddlGameNumber" runat="server" AutoPostBack="True" DataSourceID="SqlDataSource2" DataTextField="Game" DataValueField="Game">

</td></tr>
<tr><td>Yards: </td><td>

我找到了自己问题的答案！
当我继续滚动浏览许多类似的问题时，有人建议使用Response.Write命令来显示sql字符串以确保它看起来正确。我插入了一个Response.Write命令来显示连接字符串和sql字符串以验证准确性。我仍然有同样的错误。然后我明确地想出了提交按钮代码。我再次运行代码并得到相同的错误消息。这告诉我错误不在我的提交代码中。
我移动到代码的表单部分，开始注释掉文本框，并从结尾开始一次下拉列表。我在代码的这一部分中创建了sqldatasource链接之后发现我已经更改了表格中的列标题：
<asp:DropDownList name="Atts" ID="ddlAtts" runat="server" DataSourceID="SqlDataSource5" DataTextField="Game" DataValueField="Game">
</asp:DropDownList>
<asp:SqlDataSource ID="SqlDataSource5" runat="server" ConnectionString="<%$ ConnectionStrings:AttsConnectionString %>" ProviderName="<%$ ConnectionStrings:AttsConnectionString.ProviderName %>" SelectCommand="SELECT * FROM [T_Atts] ORDER BY [Game]"></asp:SqlDataSource>
一旦我在所有适用的代码部分中将Game改为Atts，它就像一个魅力！
感谢所有花时间阅读我的问题，提交答案或回答其中许多类似问题的人，这些问题引导我解决问题！

我会尝试在查询文本中使用您的参数名称：
sqlString = "Insert into T_Passing (Season, Game, Team, Player, Atts, Comps, Yards, TDs, INTs, Longest) Values (@Season,@Game,@Team,@Player,@Atts,@Comps,@Yards,@TDs,@INTs,@Longest)"
