title: How to set value for the multi-select field using netsuite suitescript 2.0 version?
body: <p>I want to set the value for the multi-select with existing values in that field. 
  (i.e) If the Filed has the values "A  , B" means I wants add the New Value "c" with Existing Values So, Result would be "A,B,C" . </p>
  
  <p>I used "N/Record' Modules SubmitFields API to set the value for the Multi-select Field like this </p>
  
  <p><strong>CODE : SuiteScript 2.0 version :</strong></p>
  
  <p><strong>Initial Code:</strong> </p>
  
  <pre><code>var strArrayValue = new Array();
      strArrayValue [0] = "A";
      strArrayValue [1] = "B";
      strArrayValue [2] = "C";
  
  
  record.submitFields({
           type:'purchaseorder',
           id:56,
           values:{
  
           custbody_multiselectfield: strArrayValue 
  
           },
           options: {
              enableSourcing: false,
              ignoreMandatoryFields : true
            }
  
  });
  </code></pre>
  
  <p>It is showing the error like this : <strong>"you have entered an Invalid Type Argument :arg 4"</strong></p>
  
  <p><strong>Updated Code :</strong> </p>
  
  <pre><code> var strArrayValue = new Array();
          strArrayValue [0] = "A";
          strArrayValue [1] = "B";
          strArrayValue [2] = "C";
  
     var PORec = record.load({               // Loading Purchase Order Recod
  
                  type:"purchaseorder",
                  id:56,
                  isDynamic: true
  
                   )};
  
          PORec.setValue('custbody_multiselectfield',strArrayValue ); // Setting Value (Array List) for Multi-Select Fields
  
          PORec.save();    // Saving Loaded Record
  </code></pre>
  
  <p>It is also showing the error: <strong>" Invalid custbody_multiselectfield'reference key 31567,31568 "</strong></p>
  
  <p>But if I add an Value as an String instead of String Array it is setting only single value (i.e) overriding the previous values. 
  Ex: Multi-select has only the "C" value instead of "A,B,C" Values.</p>
  
  <p>Can anyone help regarding this question.</p>
