Numerical simulation

I want to generate a numerical simulation in table for an equational output. I have used following code. But somehow I can’t get any output. I am very novice to Mathematica. Can anyone please recommend what change I should make?

Subscript[r, 1] := (-2 Subscript[c, 1] + \[Gamma] Subscript[c,     2] - (-2 + \[Gamma]) (-a + \[Tau] + (2 + \[Gamma]) ((\[Tau] - \ \[Tau] Subscript[\[Rho], 1])/(v \[Theta] Subscript[\[Rho], 1]))^(       1/(-1 + v))))/(-4 + \[Gamma]^2) simStep :=   Module[{\[Gamma], Subscript[\[Rho], 1],     v, \[Theta], \[Tau]}, {\[Gamma], Subscript[\[Rho], 1]} =     RandomReal[1, 2];   {\[Theta]} = 2;   {\[Tau]} = 1;   {v} = {2};   {\[Gamma]} = 0.5;   {Subscript[c, 1]} = 1;   {Subscript[c, 2]} = 1;   {Subscript[\[Rho], 1], Subscript[r, 1]}]   ```
