Hi, we have been recently updated to dynamics online CRM 2013 Fall and below js form onload property

function DisableSectionAttributes() {      function setFldDisabled(ctrl) {          ctrl.setDisabled(true);      }      function setFldEnabled(ctrl) {          ctrl.setDisabled(false);      }      var toggleSectionFlds = Xrm.Page.getAttribute('new_billable').getValue();      var ctrlName = Xrm.Page.ui.controls.get();      for (var i in ctrlName) {          var ctrl = ctrlName[i];          var ctrlSection = ctrl.getParent().getLabel();          if (toggleSectionFlds == false) {              if (ctrlSection == "Billing") {                  setFldDisabled(ctrl);              }          }          else {              if (ctrlSection == "Billing") {                  setFldEnabled(ctrl);              }          }      }  }

The above js is throwing following error:

'Unable to get property ' get label' of undefined or null reference'.

I have verified the names and labels of all the windows on the screen. The above js was working absolutely fine for last 10 months on previous version. 

Look forward to your help.

Regards

    I would suggest you press F12, start debugging and put in a break point on your javascript.

    then load the form again

    This will allow you step through the javascript line by line and find the problem variable.

    Hello,

    As you specified that the same js was working fine in previous version and is not working in CRM 2013.

    Please run the Custom Code Validation tool for CRM 2013 from this link : www.microsoft.com/.../details.aspx and check if we have any unsupported code listed due to which we are having this issue.

    Thank You
