[RESOLVED] [02/03] Drop down list error

[meef]

"Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. "

That's what it says when I press Submit on my form. Here is the portion of code:

Dim strBody As StringBuilder = New StringBuilder
 
        strBody.Append("CT Request" & vbCrLf & vbCrLf)
 
        strBody.Append("Name: " & txtName.Text & vbCrLf)
        strBody.Append("Address: " & txtAddress1.Text & " " & txtAddress2.Text & vbCrLf)
        strBody.Append("City: " & txtCity.Text & vbCrLf)
        strBody.Append("State: " & ddlStates.SelectedValue & vbCrLf)
        strBody.Append("ZIP: " & txtZIP.Text & vbCrLf)
        strBody.Append("Email: " & txtEmail.Text & vbCrLf)
        strBody.Append("Phone: " & txtPhone.Text & vbCrLf)
        strBody.Append("Fax: " & txtFax.Text & vbCrLf)
       'Drop down list right here strBody.Append("More Info: " & ddlInfo.SelectedValue & vbCrLf)
        strBody.Append("Comments: " & txtComments.Text & vbCrLf)
 
        txtTest.Text = strBody.ToString

No idea why it's giving me an error, I've used this method tons of other times here and it's worked fine.

On which line? I'm guessing one of those controls doesn't exist.

You have not from your code referred back to an instance of the StrBody object just before you say StrBody.append and just after the Dim statement.
