In this model, when a patient arrives and gets instructions, I want to see if Seat_10 in Row_1 is vacant. If it is, I want the patient to acquire the next available seat in row_1 and walked there. If Row_1 is not available, I want to check each of the subsequent rows and send the patient to the next row that has an available seat.
How do I get the current contents of Seat_10 in a row of seats?
Thanks
