"Width of component terminal (3) does not match width of connection (1)". How can I correct this error in my Voltage Source Inverter?

I designed a voltage source inverter but the error says the width of the terminal 3 does not match that of terminal 1 of the Demux. PLECS has advised changing the parameters in the C-Script. I believe the error might be in the code:

#include <stdlib.h>

#include <float.h>

#include <math.h>

#define FREQUENCY ParamRealData(0, 0)

#define OFFSET ParamRealData(1, 0)

#define INPUT_MIN ParamRealData(2, 0)

#define INPUT_MAX ParamRealData(2, 1)

#define OUTPUT_OFF ParamRealData(3, 0)

#define OUTPUT_ON ParamRealData(3, 1)

#define MOD_IDX(i) DiscState(i)

static int WIDTH;

static double time_stamp;

ANYBODY THAT CAN HELP ME REALISE HOW TO CORRECT THIS ERROR?

Unfortunately PLECS is a third party tool and you will need to pose this question on a different forum.
