Global variable not keeping value

[tfs]

I have a variable I am trying to keep the values in and I have it set
as a global variable.

<script runat="server">

Dim saveCommandText as String

Sub SortDataGrid (sender as Object, e as
DataGridSortCommandEventArgs)

response.Write("Before setting saveCommandText = "
& saveCommandText & "<p>")
If saveCommandText = "" then
saveCommandText = DataSet1.CommandText
End if
response.Write("After setting saveCommandText = " &
saveCommandText & "<p>")
DataSet1.CommandText = saveCommandtext & " order by
" & e.SortExpression

end Sub
</script>


saveCommandText gets set, but when I go to SortDataGrid after a button
is pushed, saveCommandText is blank again.

Why is this? Doesn't the system keep these variables values?

Thanks,

Tom.

This variable is global (meaning: available in all subs and functions)
for *this instance* of this page. As soon as the request is
finished, the variable becomes unavailable.

If you want this value to be available to the entire application (every user
sees the same value), store it in the Application object.
If every user should have his/her own value, use Session.
