how do I allow Users to save changes to a file

[Prattaratt]

I am designing a web site for where I work using Visual Studio Development Server, and am somewhat new to asp.net. We have a spreadsheet that we want certain individuals at a remote location to be able to view, and then also allow other individuals to be able to change. I have set the permisions as such for the restricted access pages as such:

<configuration>
  ...

  <location path="~/Members.aspx">
    <system.web>
      <authorization>
        <deny users="?" />
      </authorization>
    </system.web>
  </location>
  <location path="~/JointFiles/DriverStatus.xls">
    <system.web>
      <authorization>
        <allow users="dpratt" />
        <allow users="dpratt" verb="modifyState" />
        <deny users="?" />
      </authorization>
    </system.web>
  </location>

  ...
</configuration>

but when the save dialog comes up and you press save nothing happens. What am I missing? everything else, from login to restricted access works as planned.
