ListBox Field - Get selected values and insert to another field in Submission Form

[Altair]

I would like to know if it is possible to get the selected values in a List Box field with multiple selections:

I have tried the solution here: 

But I want to know how to get those selected values to another field.

Hi Altair you can try this code to iterate though the selected list and append to each field:

Here's my table:

 

Here's the code to be added in the Footer:

<SCRIPT>

document.addEventListener('DataPageReady', assignMultiple);
function assignMultiple() {
   /* You can modify the element ID as needed for x and y via Inspect Element/F12 */
   let x=document.getElementById('cbParamVirtual1');
   x.multiple=true;
   x.addEventListener("click", function() { 
     /* You can modify the element ID as needed for y */
     let y =document.getElementById('InsertRecordMulti_Email_Input');  
     y.value ="";
     
     var listLength = x.options.length;
     for(var i=0;i<listLength;i++){
       if(x.options[i].selected)          
           y.value = x.options[i].value + ";" + y.value;
        }     
});
  
} 
</SCRIPT>

Sample output:


Hope this helps!
