for(Payment_Term__c sourcePayment : Trigger.new){            

    opptyId = sourcePayment.Opportunity__c;
    achieveDate = sourcePayment.Achievement_Payment_Date__c;

     //When Paid change from false to true, CREATE payment on target
    if(sourcePayment.Paid__c ==true){

        //get oppty payment information
        Opportunity sourcePaymentOppty = [SELECT ID, Sales_Segment__c, Target_Owner_AM__c FROM Opportunity WHERE Id=:sourcePayment.Opportunity__c];

        //search oppty target sales segment with same year and month

Hi,

I just created a visual workflow and tried to activate but couldn't get the "Activate" button anywhere.
Could some one please guide me.

Thank You
