Question : Receiving error when submitting data to SQL Server through asp.net vb

I have a web form built in vb in the asp.net platform. The form collects data from the user then inserts the data to an SQL server through a stored procedure. The connection string is stored in the web config. I cannot figure out why I continue to receive an error "The ConnectionString property has not been initialized." I have never received this error. I am attaching the vb code behind the page. Thanks for the help.

Answer : Receiving error when submitting data to SQL Server through asp.net vb

if the only thing you want changed is 1926 to be the number, then change:

choiceContainer.num = xmlChoices[i];

to

choiceContainer.num = i;

but again, i'm still unsure what else is happening, so if you want to post the complete code and/or project files, and describe what net result you want, i'll see what i can do
