Sample Trigger:
trigger MemberSample on Member__c (before insert, before update) {
for(Member__c mem : trigger.New) {
Double var = Math.Floor((Double.valueOf(mem.End__c.getTime()) – Double.valueOf(mem.Start__c.getTime())) / (1000.0*60.0*60.0));
mem.Description__c = String.valueOf(var);
}
}
trigger MemberSample on Member__c (before insert, before update) {
for(Member__c mem : trigger.New) {
Double var = Math.Floor((Double.valueOf(mem.End__c.getTime()) – Double.valueOf(mem.Start__c.getTime())) / (1000.0*60.0*60.0));
mem.Description__c = String.valueOf(var);
}
