  Hi Everyone,

  Can anyone assist me with the below javascript code, I keep getting errors onchange event (see below image). I'm no expert on JS but I have enough knowledge to get by, but this Is causing me problems. It only errors when I select value 1 "Yes".

  "Error: Unable to get property 'setvalue' of undefined or null reference"

  Any assistance would be greatly appreciated.

  Regards
  Paul

  function allowance_test()
  {
      if(Xrm.Page.getAttribute("value1").getSelectedOption() != null){
      if(Xrm.Page.getAttribute("value1").getSelectedOption().text =="Yes")

     {
      Xrm.Page.getAttribute("value2").setRequiredLevel("required");
      Xrm.Page.getAttribute("value2").setRequiredLevel("required");
     }
   if(Xrm.Page.getAttribute("value1").getSelectedOption().text =="No")

     {
      Xrm.Page.getAttribute("value3").setRequiredLevel("none");
      Xrm.Page.getAttribute("value3").setRequiredLevel("none");
     }
   else  {    
      Xrm.Page.getAttribute("value1").setValue("");
      Xrm.Page.getAttribute("value2").setRequiredLevel("none");
    }

  }

  }

  Hi ,

  İnstead of using this code Xrm.Page.getAttribute("value1").setValue("");

  try using Xrm.Page.getAttribute("value1").setValue(null);

  don't use getSelectedOption().text, use getText() instead http://www.crmanswers.net/2014/07/dont-use-getselectedoptiontext.html

  Hi,

  Please make sure field name is correct and field is added on form.

  you can always check if field is available on form using

  if(Xrm.Page.getAttribute("value1")!=null)

  If you want to clear field value use

  if(Xrm.Page.getAttribute("value1")!=null)

  {

   Xrm.Page.getAttribute("value1").setValue(null);

  }
