Error running on tutorial 11.8- Running the Optimization #873

Input to simulate Correction according to pg 57 on Bmad & Tao tutorial:

Tao > run ! Run the optimizer Tao> set lattice base = model ! Save the model fit values in the base lattice Tao> call create_data.tao ! This will load the "true" values Tao> set var |model = |model + |design - |base ! Load the correction.

After input line: call create_data.tao, got the following:

Tao: set var steering[1]|model = 1.2e-4

Tao: set var steering[2]|model = 0.9e-4

Tao: set var quad_k1[1]|model = 0.9

Tao: set var quad_k1[2]|model = -1.05

Tao: set var quad_tilt[1]|model = 0.1 ! Also include tilt errors

Tao: set var quad_tilt[2]|model = -0.05

@sophiayang627 Problem was -form is now #form to avoid confusion with a minus sign in expressions. The tutorial files have been corrected.
