I experts , I have a JS to get values from a subform but I have a problems to get values from a couple of fields.

In the chrome console I can see the value stored in the object, but I can't pass this value to a variable as the other values that I get from the same form.

This is the piece of code that I'm using

<script type="text/javascript">
    $(document).ready(function(){
           
                parcial = $("#sub1_ver_requisicion_aprov_parcial"); //Get subform value
                console.log(parcial);
                //console.log("Salida1: " + parcial.val());
                console.log("Salida1: " + String(parcial["0"]["value"]));
                
                nivel_apro = $("#sub1_ver_requisicion_nivel_de_aprovisionamiento"); //Get subform value
                //#sub1_ver_requisicion_status
                console.log(nivel_apro);
                console.log(".val() : " + nivel_apro.val());
                console.log("id : " + nivel_apro["0"]["id"]);  
                console.log("value: " + nivel_apro["0"].value);
                
                estatus = $("#sub1_ver_requisicion_status"); //Get subform value
                //#sub1_ver_requisicion_status
                console.log(estatus);
                console.log(".val(): " + estatus.val());
                console.log("value brackets: " + estatus["0"]["value"]);
                console.log("value: " + estatus["0"].value);
               
                $(field7).val(nivel_apro["0"]["id"]); //Set field to value of subform
               
        
    })
</script>

This is the value of the field in the subform

This is the outputs from the fields nivel_de_aprovisionamiento and  status  , the first one is a field type calculation and the second is a list box.
