Once you are finished, click on the Preview link at the bottom of the page to read through your responses. When you are satisfied with your responses, then click Submit from the Preview page. You can print the form at any point by clicking the Print form.
Once you submit the form, you will see a screen that indicates that your form has been submitted. It will include two links: one is to edit your form, and one is to get a PDF of your form.
The edit button lets you edit the form as many times as you need. Each time you enter new information, however, you will need to preview and then submit the form. All your previously entered information will be there, as long as you use the edit link provided on the acknowledgement screen.
You may want to download and save the PDF to your computer and retitle it with the name of your project.
