Hey there I`m new with this reporting tool So i have database fields with values of strings (c13,c14,c15,c16)but these string values are numbers. ("3","2","1") And i need to sum all these fields values.In report i need to see c13+c14+c15=3+2+1=6 i created variables with expressions: $F{C21}==null ? "0" : $F{C21} and then used the Integer.valueOf($V{c16}) but it doesn`t worked.String and integers conflict Post edited by: megotronx, at: 2007/06/11 13:05
