    Hey guys,

    So basically I have couple of option sets from where I choose a value and based on those value I calculate the result. 
    I have 7 option sets, but it is not necessary that all 7 are used. SO if someone only chooses to use values from 3 of the option sets and leave the rest empty, the user gets the following error.

    There was an error in the field customized event.

    Event: onSave

    Error: Unable to get property 'value' of undefined or null reference. 

    now I realize that this error means that the other option set values are empty but how do I get past this?

    I am using javascript to use the value from option set to multiply to a value in text field and get my result. Here is my code

    function cashTotal()
{


if (Xrm.Page.ui.getFormType() == 1) 
{
var bill1 = Xrm.Page.getAttribute("inmate_cashbills1").getSelectedOption().value;
var bill1Text = Xrm.Page.getAttribute("inmate_cashbill1_text").getValue();

var result1 = bill1 * bill1Text;
 Xrm.Page.getAttribute("inmate_total1").setValue(result1);
 

var bill2 = Xrm.Page.getAttribute("inmate_cashbills2").getSelectedOption().value;
var bill2Text = Xrm.Page.getAttribute("inmate_cashbill2_text").getValue();

var result2 = bill2 * bill2Text;
 Xrm.Page.getAttribute("inmate_total2").setValue(result2);
 
 
 var bill5 = Xrm.Page.getAttribute("inmate_cashbillls5").getSelectedOption().value;
var bill5Text = Xrm.Page.getAttribute("inmate_cashbill5_text").getValue();

var result5 = bill5 * bill5Text;
 Xrm.Page.getAttribute("inmate_total5").setValue(result5);
 
 
 
 var bill10 = Xrm.Page.getAttribute("inmate_cashbills10").getSelectedOption().value;
var bill10Text = Xrm.Page.getAttribute("inmate_cashbill10_text").getValue();

var result10 = bill10 * bill10Text;
 Xrm.Page.getAttribute("inmate_total10").setValue(result10);

 
  var bill20 = Xrm.Page.getAttribute("inmate_cashbills20").getSelectedOption().value;
var bill20Text = Xrm.Page.getAttribute("inmate_cashbill20_text").getValue();

var result20 = bill20 * bill20Text;
 Xrm.Page.getAttribute("inmate_total20").setValue(result20);
 
 

 

 var tmp = result1 + result2 + result5 + result10 + result20;
 
 Xrm.Page.getAttribute("inmate_cashtotal").setValue(tmp);

}

    Basically "inmate_cashbills1" is the value from option set.
    "inmate_cashbill1_text"  is a value that is multiplied by the option set value to give a result.

    I found the solution. Instead of

    var bill1 = Xrm.Page.getAttribute("inmate_cashbills1").getSelectedOption().value;

    DO 

    var bill1 = Xrm.Page.getAttribute("inmate_cashbills1").getValue();
    Still thank you for your help

    The simplest way would probably be to do a try catch around each or to evaluate the value of the option set prior to using it.

    Why would I do a try catch? 

    I know the error and the reason behind the error. I just want to know what to do if I DONT WANT TO USE ALL the option set and calculate my result based on one or two of them?

    The try catch is just a way to evaluate and keep going...you're not actually doing anything with the exception...

    try{
    var bill1 = Xrm.Page.getAttribute("inmate_cashbills1").getSelectedOption().value;
var bill1Text = Xrm.Page.getAttribute("inmate_cashbill1_text").getValue();

var result1 = bill1 * bill1Text;
 Xrm.Page.getAttribute("inmate_total1").setValue(result1);
 }
    catch(e){}

    try{
var bill2 = Xrm.Page.getAttribute("inmate_cashbills2").getSelectedOption().value;
var bill2Text = Xrm.Page.getAttribute("inmate_cashbill2_text").getValue();

var result2 = bill2 * bill2Text;
 Xrm.Page.getAttribute("inmate_total2").setValue(result2);
    }
    catch(e){}

    it starts giving me another error "you need to choose the enter value between 0 and 1,000,000,000" and then it closes the form. It is catching an exception of the field when i do not use one of the option set.
