Hello, i just got the same problem. The labels overwrites themselves and so i cant read anything. Picture in attachment shows this. Thanks in advance.

Thank you, but i already found this mistake, if u check the edit in my last post. I dont get any errors now. But the result is still null and not what i need. Any other ideas?

i made a mistake changing the language. Now i really changed the language to Java and i get an other error. The left-hand side of an assignment muss be a variable: ($V{totaldowntime}=null ? 100 : 100-$V{totaldowntime}/2592000*100 ) this means for me that left of the : has to be variable like $V{availability}=100. But this dont work too. then i get the message: Syntax error on token "=", != expected : ($V{totaldowntime}=null ? $V{availability}=100 : $V{availability}=100-$V{totaldowntime}/2592000*100 ) when i change this like in the message. i get again the error that The left-hand side of an assignment muss be a variable. So where is my real mistake now? edit i changed $V{totaldowntime}=nullto $V{totaldowntime}==null so i dont get the message. but as result i get null too. so this dont really work :( Post Edited by nicoheber at 05/06/2011 09:17

I changed the language from <Template Default> to Java and i dont see any changes in the report. So this cant be the problem. Maybe i did a mistake in the user defined expression, did i used it wrong?

Hey guys, i have a problem with conditions in variables. I want to show the availabilities for some routers in a report. For this i created a master and a subreport. In the subreport i select the data for a router. When there are data, theres no problem. But when there are no data it only shows null for my calculations. I have two variables. The first is totaldowntime which sums all downtimes. The second calculates the availability with the formula: 100-$V{totaldowntime}/2592000*100. This works when there are data. But i want something like ( $V{totaldowntime}=null ? 100 : 100-$V{totaldowntime}/2592000*100 ) from the user defined expression ( <condition> ? exp1 : exp2 ). But this dont work, i get the error: Errors compiling D:\Documents and Settings\heber\My Documents\ireports\Standortverfügbarkeit_subreport1.jasper!
