To see the list of results from any of your webforms, click on the Webform link in the main menu.
Next, choose your webform from the list by clicking the Results (or the number of submissions) link.
At this point, you'll get a page showing all the submissions to your webform and a menu of options.
You can click on View, Edit or Delete to do any of those functions on each individual submission.
If you select Table, you'll get a page with a grid of all the data submitted for the form.
If you select Download, you'll be able to download an Excel spreadsheet or CSV of the data for your own perusal later.
