Thomasm Trigger to update field on master-detail
I am looking for some help on a trigger to update a field. I have 3 custom objects (job, Employee, and Employee form). the job is the master to the employee and the employee is the master to the employee form. I have a number field called hats on the job object and when a employee form is created i want to use the quantity field to update the hat field.
So far i have the following but i am getting the error "Initial term of field of expression must be a concrete object".
trigger updateHats on Employee_Forms__c (before insert) {
set<id> jobids=new set<id>();
map<id,jobs__c> jobsmap=new map<id,jobs__c>([select id, hats__C from jobs__c where id=:jobids]);
//List<Jobs__C>Jobs=new list<jobs__c>();
For(employee_forms__C b:Trigger.new)
if(b.Uniform_Type__C=='Hat')
{
jobsmap.hats__C= jobsmap.hats__C - b.Quantity__C;
}
}
I think its because the job and the employee form object are not directly related but i am not sure and if i was sure i am not sure how to go about fixing it.
Any help i would appreciate
