Hi, I want to perform a simple calculation on my Vf page. I have an integer countCompleted and a decimal auditsToBeMade variable on the controller side.public Integer getcountCompleted(){ Integer countCompleted = [select COUNT() from Financial_Audit_Plan__c where YTD_Completed_Audits__c = 1 AND ((DM1__c = :userInfo.getUserID()) OR (DM2__c = :userInfo.getUserID()) OR (DM3__c = :userInfo.getUserID()) OR (DM4__c = :userInfo.getUserID())) AND Calendar_year(Planification_Date__c) = :System.today().year()]; System.debug('Total is '+countCompleted); return countCompleted; }public Decimal getauditsToBeMade(){ if(financial1!=null && total_size!=0) auditsToBeMade = financial1[0].Total_Planned_Audits__c; return auditsToBeMade; }I just want to dispaly something like this. ({!countCompleted}/{!auditsToBeMade})*100% on the page. I tried by creating a new variable on the controller and performing calculation there and then displaying that variable on the page.: public Decimal getpercentAudit(){ if(auditsToBeMade!=0){ Decimal percentAudit = (getcountCompleted()/getauditsToBeMade())*100; System.debug('Percent is '+percentAudit); return percentAudit.setScale(2, RoundingMode.HALF_UP); }else{ return null; } }But I get an exception whenever getauditsToBeMade() method doent return any value, how can i prevent this error? Please advice.Thank you
