Would you be able to help me figure out what I'm doing incorrectly.

I have a cascading drop down in a submission form that has multiselect enabled (Services).

What I want it to do, is that the values of the selected service, be copied to the Description Field as values separated by a comma.

Here is the scripts I'm using. It just generates a value of "undefined," so I know something is wrong, but I can't figure out what. Any help is greatly appreciated.

 

 

var x=document.getElementsByName("InsertRecordServices");

x[0].multiple=true;

document.getElementsByName("InsertRecordServices")[0].onblur = function ()

{

document.getElementById("InsertRecordDescription").value = document.getElementsByName("InsertRecordServices").value;

}

Add the code below to the header of the page:

 

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>

<script>

window.onload = function multiselect() {

var a = document.getElementsByTagName('select');

var index;

for (index = 0; index < a.length; ++index) {

          if (a[index].size!==0) {

    a[index].multiple=true;

          }

}

}

</script> 

 

And this code to the Footer

 

<script>

$('[name=InsertRecordServices]').change(function() {

$('[name=InsertRecordDescription]').val($('[name=InsertRecordServices]').val())

});

</script>
