Rashida!! Thank you!!!!!!!!! You have turned a long frustrating day into a good one.
I did go so far as to look at the template options, but ...... I guess I was tired, it didn't even occur to me to turn on elements.
I've installed the Helix template numerous times, and it's always automatically come in prepopulated with a number of elements. Did I do something wrong, or neglect to do something I should have (or have you changed your procedure)?
In any case, thank you again for your very rapid reponse, for fixing the basic elements, and for forwarding on some hint images to guide me. I do know my away around that menu, but I appreciate your thoughtfulness.
