"Object reference not set to an instance of an object.

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

vb Code:
  1. Dim strBody As StringBuilder = New StringBuilder

  2.  
  3.         strBody.Append("CT Request" & vbCrLf & vbCrLf)

  4.  
  5.         strBody.Append("Name: " & txtName.Text & vbCrLf)

  6.         strBody.Append("Address: " & txtAddress1.Text & " " & txtAddress2.Text & vbCrLf)

  7.         strBody.Append("City: " & txtCity.Text & vbCrLf)

  8.         strBody.Append("State: " & ddlStates.SelectedValue & vbCrLf)

  9.         strBody.Append("ZIP: " & txtZIP.Text & vbCrLf)

  10.         strBody.Append("Email: " & txtEmail.Text & vbCrLf)

  11.         strBody.Append("Phone: " & txtPhone.Text & vbCrLf)

  12.         strBody.Append("Fax: " & txtFax.Text & vbCrLf)

  13.        'Drop down list right here strBody.Append("More Info: " & ddlInfo.SelectedValue & vbCrLf)

  14.         strBody.Append("Comments: " & txtComments.Text & vbCrLf)

  15.  
  16.         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.
