Inline C# Script Not working

I am trying to do a client-side script to make a row appear/disappear when the users clicks on a radio button.  I was going to do this in JavaScript, but got to reading about putting inline C# into the code, so thought I would try that for consistency (also some people turn off JavaScript in their browser).

Anyhow, I can't get it to work - have tried modifying it every-which-way and it is either not firing at all (current state) or it is giving me an error: "Microsoft JScript runtime error: 'ShowRows' is undefined.

The script code is as follows:

<head id="Head1" runat="server">
  <script type="text/C#" runat="server" language="C#">
        protected void ShowRows()
        {
            if (rbCategory.Checked)
            {
                trLocation.Visible = true;
                trSortOrder.Visible = false;
                txtSortOrder.Text = "0";
                ddlSubcategory.SelectedIndex = -1;
            }
            else
            {
                trSortOrder.Visible = true;
                trLocation.Visible = false;
                cbSchaumburg.Checked = false;
                ddlPrograms.SelectedIndex = -1;
            }
        }
    </script>
</head>

...and this is the portion of the code containing the controls that call it:

   <tr>
      <td align="left" valign="top" colspan="2"><p><strong>The 
          Degree/Certificate/Credential/Concentration named above:</strong></p>
          <asp:RadioButton ID="rbCategory" runat="server" GroupName="degreeType"
