Hi, I think I might be doing something wrong. I am using Visual Web Developer 2010. I am trying to get a error message to pop up but the program keeps saying that 'Show is not a member of Messagebox' and I really don't know what to do. Here is the code below. I would really like if someone could point me in the right direction, please. Then error message code is at the bottom, Thanks.
