I know I can trigger a workflow if a record is changed but I want to trigger a workflow if a record has a certain indicator. Here is the example I have. I create a new case and one of the fields in the case is "State of Equipment" and the options are "good" "ok" "fair" "obsolete". If the person indicates that the equipment is obsolete and saves the record I want it to trigger a workflow. I do not want it to trigger a workflow in an other state.
