Hi Raj,

I tried this code  
trigger DocumentAttached on Task (before update) {
    // "after insert" won't work for sure. 
    // It's pretty much guaranteed to have 0 attachments there 
    // (well, unless you have other triggers but let's not go down that rabbit hole)
    // also - in "after" triggers you can't modify the original record directly, 
    // "before" is better for what you're trying to do

    for(Task t : [SELECT Id,
        (SELECT Id FROM Attachments LIMIT 1)
        FROM Task
        WHERE Id IN : trigger.new]){

        trigger.newMap(t.Id).Questionnaire_attached__c = !t.Attachments.isEmpty();
        // looks like black magic but should work ;)
    }
}

but I am not sure Questionnaire_attached__c  what this field is all about due to this I am getting error.​
