I get the above error message when running the following code:

```
[Alpha]h = 0.2; [Alpha]z = 0.2; [Gamma] = 0.5; ph = 0.01; pf =
0.1; pE = 0.05; FC = 0.1; FE = 0.15; tC = 0.01; tE = 0; TC = 0.05; TE

1 / (1 - [Rho]); L = 1; RA = 0.25; [Mu] = 1;
G = 1; R0 = 0.1; S = 1;
v[s_] : = [Mu] log[
Exp[([([([([Alpha]h ((RC[s] +
ph) ^ (- ([Rho]/ [Sigma])) + ([Alpha]H / [Alpha]z) ^ (- (

sol = FullSimplify[Tosolve[{D[v[Solve[{D[v[LĂ¶sen[{D[v[Solve[{D[v[s]s]== 0}, RC & # 39;[s]]]solprime = Equal Flatten[sol];
solND = NDSolve[{solprime[[1]], RC[S] == RA}, RC, {s, 0, S}]
```

I tried to add the suggested method as well as the method -> {"EquationSimplification" -> "Solve"}, but got some other error messages after some time of calculation.

Either "NDSolve :: idelay: The initial history must be specified for all variables for delay differential equations." or "StringForm :: sfr: Element 2" requested in "Delayed time `1`

= `2`

calculated by `3`

= `4`

not evaluated to a real number. "out of range; 1 article available."

Any advice would be very grateful. Many Thanks!
