Thanks Bob, the reports in question originated in Qa4. They were originally made in the flowersheet database. When I copied that database and modified it to create the endowment database, the reports came along for the ride, I don't need them, and they have now been deleted.

I am struggling with your use of the term "fields".  This is commonly misused in Sesame discussions.  But the distinction is important to help diagnose the problems.

In Sesame, fields are generally seen only when Managing Database.  What you see on your forms are referred to as Layout Elements (LE).  They are "bound" or connected to invisible database fields.

So, when you lose your "fields", do you really mean the fields or do you mean the LEs?

In the Database Manager you can expand each of the fields and see every form that is bound to that field.

In the Deisgner on the Form, you can check to see what fields each LE is bound to.

What do you mean by 'code' fields
It sounds like perhaps you have some unbound LEs.  Can you redefine the problem using the terms LE and Field as defined above, and perhaps explain what symptom you have that makes you think they have vanished.  What  screen are you on?  What windows are looking at?  What are you trying to do when the "fields" vanish?

Ok, problem solved, but I don't know how.
I went in, and saved the whole works as a new aplication, then tried again, and it worked.
I'll get the hang of it sooner or later
