No popups and error source is rdr=cmd.executereader();

Question

This is the OrderDetails page and after a successful purchase at shoppingcart will be brought to this page. 1) When I let the code run, the javascript popup didn't popup like it did for my other pages. 2) rdr=cmd.executereader() was the error leading to an error page 3) SELECT * OrdersView was another error. [ I edited to SELECT * FROM ordersView] * NEW ERROR * 4) All this codes gives me no error anymore. But there's no popup and there's no email being sent to the account.

My pov on this error: Some analysis. I tried both the string StrFirstName part alacartely and the session["sfirstname"] alacartely too both result in the same error. So I post the both of the extract for you to see.

I'm not really that good in c# but I believe its due to either I retrieved the database using * instead of FROM and also cause I didn't retrieve the parts I need correctly (Logic error, I presume) Anyone can direct me on this issue?

Answer 1

Well for a start

SELECT * ordersView

should be

SELECT * FROM ordersView

Your code as it is would not return anything to rdr because the syntax is wrong.

This is more than likely the problem But you aren't giving us the actual errors which we would need if this is not the answer.
