Developement Trigger - Attachment
Hello,
I have this Trigger that update the checkbox to true if an Opp has an attachment. This Trigger work fine.
trigger Att_Aft_Trig on Attachment (after insert, after update)
{
List<Opportunity> co = [select id, Attachement__c from Opportunity where id =: Trigger.New[0].ParentId];
if(co.size()>0)
{
co[0].Attachement__c = true;
update co;
}
}
But I want to know if I remove the Attachment the checkbox should be unchecked?How should I do this in this trigger?
Thanks,
Shruti
