trigger FindDupes on Lead (before insert, before update) { for (Lead myLead : Trigger.new) {
if (myLead.Email != null) {
List<Contact> dupes = [SELECT Id FROM Contact WHERE Email = :myLead.Email];
if (dupes.size() > 0) {
myLead.Dupe_Contact__c = dupes[0].Id;
} else {
myLead.Dupe_Contact__c = null;
} }
} }
but its gives error
