Hi,

Can you show us the code that generates this error?

Cheers!

Check your code. It looks like your query is including the text "System.Web.UI.WebControls", and rejecting it as having too many prefixes.
Show us the code that builds your SqlClient.SqlCommand

The thirdline of the error shows that the problem is in line 139 of Register2.aspx
"ASP.register2_aspx.Insert2(Object sender, EventArgs e) in register2.aspx:139"
I would check out this line for your problem.

If that does not help then post your code as planeswalk suggested above.

You're probably giving the name of your control to your query instead of the value of the control.

Use:

sql = "select ....." + ....;
and then put a watch on your sql string, you'll find your error quite quick.
