Hi, I put this question into ireport forum and mdahlman suggested me to send here this question : This is a very new new dummy in ireport, and I have to search the way of doing this : instead of call for a VarA=new String("1") and VarB = new String("2") and obtein VarA+VarB = 3 on an excel result from ireport I have to obtein: VarA VarB =VarA+VarB (But, this value shold auto generate when it is opened the formula, that is instead of send the value, send the formula) Well in excel you have autoformula but It is checked and no way, It does not work , so if I send VarA as string, varB as string , the "=vara+varb" as string due to if I send it as a integer, It does not work, so... Is there another way of getting the autoformula into the excel ??? I have to choose another kind of object for the variable, It is about a property into the excel ???? Futhermore , I have a report on ireport and this report has a field VarA="=sum(D1:D2)" Well, this report should show the number instead of the formula, but I have to send the formula from ireport to excel when I choose generate on EXCEL . I try with string and with a \n on the VarA, but I does not work, I looking for excel forums, but I does not tell me anything about this issue, Could any body help me please ? If anybody can help me , please, It could great...I think this is very useful to know.. Thanks in advance Code:in a field I put "=sum(D1:D2)"
