Where are your fv,av etc defined at? Exact steps?

In prior version (5443?) I could enter following in CAS:

F_A1:=fv=av*((1+rate)^per-1)/rate;
Solve.E1:='F_A1';

fv, av etc. are not defined at this point...

Then when I opened Solve App, I could click on E1** then Num. It would ask me if I wanted to create variables fv, av etc. and I click OK. From here, I could SOLVE for any variable.

** The only difference with new firmware is that E1 initially shows "Error: Syntax Error".
