I am working on a workflow rule
(Opportunity: Opportunity Record Type EQUALS Express Program,Express Post-Compliance) AND (Opportunity: StageEQUALS Awarded) AND ((Opportunity: Sub-StageEQUALS New Contract) OR (Opportunity: Sub-StageEQUALS null))
This is the Rule Criteria and it works while creating records with each of the Record Types,Stages and Substages.Even while keeping the substage as null it works and I have kept an immediate email alert and I receive the email immediately.
But if I update the records to meet all of these rule criteria it is not working.
Evaluation Criteria:Evaluate the rule when a record is created, and any time it's edited to subsequently meet criteria
