Dear all,

I am trying to write a simple trigger that will update child custom object fields from a parent (Account) record.

When I save the record it seems to make the fields null. Can anyone suggest anything? Probably something very simple I just can't see it.

trigger ElecPassME1ME2Team on Electricity_Meter__c (after insert, after update) {

    For(Electricity_Meter__c Elec: Trigger.New){
        Elec.Sales_Team__c = Elec.Account__r.Team_s_Dept_s__c;
        Elec.ME1__c = Elec.Account__r.ME1__c;
        Elec.ME2__c = Elec.Account__r.ME2__c;  
    }
