HP Prime: CAS variable to Solver error message

[CR Haeger]

Hello,

Prior to firmware update, this workaround allowed a CAS equation to be written, assigned to Solver.E1 then numerically solved for term(s):

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

which would (1) load fv=av*((1+rate)^per-1)/rate into E1, (2) promt to create user variables (yes) then (3) allow for numerical solving.

------

Since firmware update, E1: shows Error: Syntax Error. It shows this until after steps (2) and (3) completed, then will start showing the formula.

This threw me off, thinking I had a non valid equation being sent to Solver. I hope this can be fixed, or perhaps suggest better workarounds for creating equations then solving using Solver App.
