Compiler Error Message: BC30455: Argument not specified for
parameter 'e' of 'Public Function UpdateDataStore(e As
System.Web.UI.WebControls.DataGridCommandEventArgs) As Boolean'.

I got this code from Sams teach yourself asp in 21 days page p366 but
it doesnt seem to work.
Here is the subroutine:

Sub MyDataGrid_Update(Sender as object, e as DataGridCommandEventArgs)

If UpdateDataStore then
FillDataGrid(-1)
End if
MyDataGrid.DataBind()
End Sub

SHouldn't it be if updatedatastore is equal to something? Its a
boolean.

Here is the subroutine it calls:

function UpdateDataStore( e as DataGridCommandEventArgs) as boolean
dim i,j as integer
dim params(7) as string
dim strText as string
dim blnGo as boolean= true
j=0
for i=1 to e.item.cells.count-3
strText=Ctype(e.item.Cells(i).Controls(0),TextBox).Text
if strText<>"" then
params(j)=strtext
j=j+1
else
BlnGo=false
'lblmessage.text=lblMessage.text &"You forgot to enter a value<p>"
end if
next
if not Blngo then
return false
exit function
end if
dim strSQL as string
strSQL="Update chasers set Name='" & params(0)
& "',Emailaddress='" & params(1)& "',Message='" & params(2)
& "',Frequency='" & params(3)& "',Times='" & params(4)
& "'Start_date='" & params(5)& ",'Number='"
strSQL=strSQL & params(6) & "' WHERE USERID= " & Ctype
(e.Item.Cells(0).Controls(1),Label).text
ExecuteStatement(strSQL)
response.write(Blngo)
Return BlnGo
End Function
