If you have other way to do it, will be happy to hear about it too.

I’m adding the code, you can see part of the code is regarding the History (left it so you can compare), I’m missing the part that sign in yellow.

var CRM_FORM_TYPE_CREATE = 1;
var CRM_FORM_TYPE_UPDATE = 2;
var CRM_FORM_TYPE_READONLY = 3;
var CRM_FORM_TYPE_DISABLED = 4;
var CRM_FORM_TYPE_BULKEDIT = 6;
var CRM_FORM_TYPE_UNDEFINED = 0;

// Test the FormType and ObjectId properties.
switch (crmForm.FormType)
{
   case CRM_FORM_TYPE_CREATE:
   case CRM_FORM_TYPE_BULKEDIT:
   case CRM_FORM_TYPE_UNDEFINED:
   {
      document.all.IFRAME_HistoryFrame.src="about:blank";
                  document.all.IFRAME_RE.src="about:blank";
      break;
                }
   case CRM_FORM_TYPE_UPDATE:
   case CRM_FORM_TYPE_READONLY:
   case CRM_FORM_TYPE_DISABLED:
   {
                                document.all.IFRAME_HistoryFrame.src="/sfa/accts/areas.aspx?oId=" +
                                crmForm.ObjectId +
                                "&oType=1&security=852023&tabSet=areaActivityHistory";

                                document.all.IFRAME_RE.src="/sfa/accts/areas.aspx?oId=" +
                                crmForm.ObjectId +
                                "&oType=1&security=852023&tabSet=????";
                  break;
                }
}

Thanks,
