I am creating an application in Ionic using Angular and I have the following Form

this.CalcLecheForm = this.formBuilder.group({
      cedula:['', [Validators.required]],
      propietario:['',[Validators.required]],
      finca:['',[Validators.required]],
      latitud:[this.lat],
      longitud:[this.lon],
      altitud:[,[Validators.required]],
      extension:[,[Validators.required]],
      emisiones_co2_totales: [this.co2_eq_totales]
    })

How can I show what total_co2_emissions contains in the following grid when I click on a calculate button?

<ion-grid fixed class="grillasalida">
           <ion-row> 
            <ion-col size="6" size-sm>Parametro</ion-col>
            <ion-col size="3" size-sm>Valor</ion-col>
            <ion-col size="3" size-sm>Medida</ion-col>
          </ion-row>
          <ion-row class="ion-align-items-center">
            <ion-col size="6" size-sm>Emisiones de CO2-eq totales</ion-col>
            <ion-col size="3" size-sm> (Aqui iria el valor de emisiones_co2_totales )</ion-col>
            <ion-col size="3" size-sm>kg CO2-eq/año</ion-col>
          </ion-row>
          <ion-row>
            <ion-col size="6">
              <ion-fab-button fablimpiar data-desc="Cancelar" (click)="CancelCalc()" [disabled]="!CalcLecheForm.enabled">
                <ion-icon name="close-outline"></ion-icon>
              </ion-fab-button>
            </ion-col>
            <ion-col size="6">
              <ion-fab-button fabguardar (click)="Calc()" data-desc="Calcular" [disabled]="!CalcLecheForm.valid">
                <ion-icon name="save"></ion-icon>
              </ion-fab-button>
            </ion-col>
          </ion-row>
 </ion-grid>

I am creating a patient management system with Angular and TypeScript and using FormControlNameas shown in the following code:

ngOnInit() {

    this.formularioPaciente = this.fb.group({
      TipoDocumento: ['', Validators.required],
      NumDocumento: ['', Validators.required],
      urlImg: [''],
      PNombre: ['', Validators.required],
      SNombre: [''],
      PApellido: ['', Validators.required],
      SApellido: ['', Validators.required],
      Genero: ['', Validators.required],
      FechaNacimiento: ['', Validators.required],
      Edad: [] ,
      EstadoCivil: ['', Validators.required],
      RH:['', Validators.required],
      EPS: [''],
      Departamento: ['', Validators.required],
      Municipio: ['', Validators.required],
      Zona: ['', Validators.required],
      Barrio: ['', Validators.required],
      Direccion: [''],
      Telefono: [''],
      Email: [''],
      NomPadre: [''],
      NomMadre: ['']   
    })
  }

The point is that to calculate the value of the Age Field I am using the following function using the moments js library:

calcularA(){
    this.formularioPaciente.value.FechaNacimiento = moment(new Date(this.formularioPaciente.value.FechaNacimiento));
    let fechafin = moment(Date.now());
    let diff = fechafin.diff(this.formularioPaciente.value.FechaNacimiento, 'year');
    return diff;
  }

How can I assign the Value of my function calcularA()to the field Edadof my FormControlNametry as follows:

Edad:[this.calcularA()]but it generates an error that tells me value is undefined, please help me I'm stuck.
