def op

if ( ipval == "emvipperr" )
{
def bck = ctx.payload.aggregations.dateRange.buckets[0]
op = "

EMV IPP Error Details:

"
op += ""
op += ""
op += ""
bck.timeRange.buckets.each {
k ->
def millis = ky
def timeofOcc = new Date(millis).format("yyyy-MM-dd HH:mm:ss.SSS")
k.user_Id.buckets.each {
ki ->

		op += "<tr><td style='padding:5px;padding-left:20px;padding-right:20px;background-color:#F9F9F9'>${timeofOcc}</td>"
		op += "<td style='padding:5px;padding-left:20px;padding-right:20px;background-color:#F9F9F9'>${ki.key}</td>"
		op += "<td style='padding:5px;padding-left:20px;padding-right:20px;background-color:#F9F9F9'>${ki.doc_count}</td></tr>"
	}
}
