In the attached model, a Global Variable, "Count_Not_Triaged," is incremented and decremented to keep track of the number of patients that have not yet been triaged. Then, in Activity 46 of each of the five Patient Tracks, which nurse is to be used when it comes time to do triage is determined by the value of the Count_Not_Triaged variable. If the value of the variable is less than 12, then a nurse is selected from a primary group of nurses. If it's greater than 12, then a nurse is selected from an Alternate Group which includes members of the primary group plus one additional nurse. The selection is determined by the "Based on a Condition" Staff Requirement menu option as shown below.
Unfortunately, the selection process doesn't seem to be working as the alternate nurse is never used even when the "Count_Not_Triaged" exceeds 12. What am I missing?
