Hi Larry,
It sounds like this might be the first time that you have opened to Site Designer to make an edit. By default, the first time that you open the site designer the Quick Setup Theme Wizard will appear on the right-hand side. There should be a button at the bottom of that menu to Finish the setup wizard. Once you have closed that menu, you should be able to access the Build menu, which will allow you to customize the widgets in your site.
If you have already closed the Quick Setup Theme Wizard and are still having trouble, it's possible that your account does not have access to make changes to the site design. In that case, you will need to reach out to your administrator about altering your role permissions.
Hope this helps!
