Auto Populate lookup fields based on another lookup field value

Hi,

I have two objects A & B. I have 4 lookup fields on object A with object B. When I select lookup field value in first field; I want all the other 3 lookup fields to be autopopulated. (All the three are user fields on object B which are looked up in object A). How to accomplish this? Thanks in advance!

Is it possible to use three different formula fields to get the values from the Parent object.

If not you can write your own apex trigger for this.

<code>
trigger myTrigger on ObjectA__c(before insert, before update){
    for(Object A obj : Trigger.new){
        if(obj.Lookupfield__c !=null){
            obj.secondLookUp = obj.LookupField__c;
            obj.thirdLookup = obj.lookupfield__c;
            obj.fourthlookup = obj.lookupfield__c;
        }
    }
}

</code>

I have a similar problem but my trigger has errors
I have custom Object Propuesta__c with two lookup fields, Opportunity__c and Account__c
I want that Account__c gets populated with the AccountId related in the Opportunity__c

I tried the following:
trigger propuesta_cuenta on Propuesta__c(before insert, before update){
    for(Propuesta__c prop : Trigger.new){
        if(prop.Opportunity__c !=null){
            prop.Account__c = prop.Opportunity__c.AccountId;
        }
    }
}

but get error: Error: Compile Error: A non foreign key field cannot be referenced in a path expression: Opportunity__c at line 4 column 36

Any help?
thanks
