displayname=Latest Update
namekey=latest update
textmode=true
valueexpression=IF(LEN({lastNote}.{noteText})>140, CONCAT(SUBSTR({lastNote}.{noteText},0,139),"...(open for more) -- ", {lastNote}.{owner}.{name}," on ", {lastNote}.{entryDate}), IF(LEN({lastNote}.{noteText})>0, CONCAT({lastNote}.{noteText}," -- ", {lastNote}.{owner}.{name}," on ", {lastNote}.{entryDate})))
valueformat=HTML
