using loops in process flow with labels

Hi everyone. I'm making some changes based on the people-based model tutorial. I attached two labels to each patient, finishedturns and wholeturns, recording the number of turns of care a patient has received and the amount of turns of health care a patient needs, respectively. After finishing a health care, it should be decided whether a patient needs further care, or the times of health care (finishedturns) has met the number needed (wholeturns) for a patient, thus making a loop. "Exception: FlexScript exception: label finishedturns doesn't exist on token" occured when running the model. I noticed that some similar models refer to people in the process flow as "token.Person", while it doesn't seem to work in my model and I use "current", not sure is this relevant to the problem I meet.

In the Assign Labels you're assigning the label to current (the patient), but in the Decide activity you're looking for the label on the token, so you have a mismatch. Either assign the label to the token or change the Decide to look for the label on current.

Here's your model where I changed it to assign the label to the token:

hc_1.fsm
