Error handling for input file is not informative

If there is a mistake in the input file, the error handling does not help with fixing it.

E.g., try this file for nonlinear:

Hyperbox States : [1 2], [2 3], [3 4]
Hyperbox Disturbances : [1 2], [2 3], [3 4]
Dynamics : x1**2+u1+d1, x2+x1*x3**2+d2, x3*sin(x1)+u2+d3
Controller : -x1**2 - x1**3, -x3*sin(x1)-x3
Triggering Condition : -x1**2 - e1*sin(x2)
Triggering Times : 5
Lyapunov Function : -x1**2 - sin(x2)
Solver Options :
Linesearch Options : 1, 2, 3

This is the error message that I get:
Incorrect syntax on line: 9
