I need detail instructions on creating a customize new form to take parameters from Query string in SP designer 2010.  I follow the direction below but I am not able to edit the new form I created by deleting the list view and delete the controls by selecting the area in the design view.

Open SP Designer

go to the list and libraries and open the list

Click on the new form and create a new insert view by creating the name of the form

Open the new form I created

I am not sure how to delete the list view and make that empty, delete the control by selecting the area in the design view

I am not sure how to go to SharePoint control and add the custom list

I am not sure how to add the parameter field to get the comments form the query string.
