How To Setup SelectParameters Programmatically?

Hi,

I am using Visual Web Developer 2005 Express Edition.

I am trying to SELECT three information fields from a table when the Page_Load take place (so I select the info on the fly). The refering page, sends the spesific record id as "Articleid", that looks typically like this: "http://localhost:1424/BelaBela/accom_Contents.aspx?Articleid=2". I need to extract the "Article=2" so that I can access record 2 (in this example).

How do I define the SelectParameters or QueryStingField on the fly so that I can define the WHERE part of my query (see code below). If I remove the WHERE portion, then it works, but it seem to return the very last record in the database, and if I include it, then I get an error "Must declare the scalar variable @resortid". How do I programatically set it up so that @resortid contains the value that is associated with "Articleid"?

My code is below.

Thank you for your advise!

Regards
