I really can't see what's wrong here, I would appreciate if someone can see what's wrong and led to the error in the assignment

var PulseGenerator1 = new `simulink/Sources/Pulse Generator`;

var scope = new `simulink/Sinks/Scope`;

//var DoorMF = new `simulink/Sinks/Scope`;
var If = new `simulink/Ports & Subsystems/If`;

var Ifaction = new `simulink/Ports & Subsystems/If Action Subsystem`;

var Ifactiontwo = new `simulink/Ports & Subsystems/If Action Subsystem`;

var sensor = new `simulink/User-Defined Functions/MATLAB Function`;

var UnitDelay = new `simulink/Discrete/Unit Delay`;

var Door = new `fuzblock/Membership Functions/Trapezoidal MF`;

//assert(SubSystem.all.size() = 1);

Door.name = "door_sensor";
//assert(sensor.name = "door_sensor");

Door.script = "function y = door_sensor(u) \\n y = u;";
//assert(sensor.script = "function y = fcn(x) \n y = u;");

PulseGenerator1.position = "[125 174 155 206]";

UnitDelay.UnitDelay = 1;

If.Inputs = 2;
//If.Outputs = "2";
//If.outputs = 2;

// Link them

PulseGenerator1.link(sensor);
PulseGenerator1.linkTo(scope);
sensor.link(Door);
Door.link(UnitDelay);
Door.link(If, 1);
UnitDelay.linkTo(If, 2);

Hi Abdelgafar,

Could you please try to trim down your program to the bare minimum statements you need to demonstrate the issue you are encountering as discussed in [1]?

Thanks,
Dimitris

Hi again,

If you need to embed code in future messages, please use a code environment (last tool in the formatting toolbar) for better readability and to avoid auto-formatting issues (e.g. automatic replacement of double spaces with single spaces, which seems to be the case in Membership Functions). Also please avoid using the "topic description" field and include your full message in the body of the post.

Best,
Dimitris
