    Hi

    You are using unsupported way of customization (accessing HTML DOM elements using ids).

    The element ids might have changed or so.

    Please convert your code by using SDK Library (Xrm.Page or Xrm.Utility namespaces).

    Please refer the following (read the Important note at the top):

    I just checked but everything seem to be fine

    onLoad: function HideActivities() {

    var ctrlElement = document.getElementById(“header_notescontrol”);

    if (ctrlElement.children != null && ctrlElement.children.length > 0) {

    for (var ele = 0; ele < ctrlElement.children.length; ele++) {

    var ctrl = ctrlElement.children[ele];

    if (ctrl.title == “ACTIVITIES”) {

    ctrl.style.display = “none”;

    if (ele + 1 < ctrlElement.children.length) {

    ctrlElement.children[ele + 1].click();

    return;

    }

    else if ((ele – 1) >= 0) {

    ctrlElement.children[ele – 1].click();

    return;

    }

    }

    }

    }

    }

    and

    function deleteActivitiesTab() {

    var ctrlElement = document.getElementById("header_notescontrol");

    if (ctrlElement.children != null && ctrlElement.children.length > 0) {

    for (var ele = 0; ele < ctrlElement.children.length; ele++) {

    var ctrl = ctrlElement.children[ele];

    if (ctrl.title == "ACTIVITIES") {

    ctrl.style.display = "none";

    if (ele + 1 < ctrlElement.children.length) {

    ctrlElement.children[ele + 1].click();

    return;

    }

    else if ((ele - 1) >= 0) {

    ctrlElement.children[ele - 1].click();

    return;

    }

    }

    }

    }

    }
