How can I debug pre-run script and monitor it when it is running?

I am trying to do calibration using pre-run script.
The code below does not work which is kind of expected because I am still trying to figure this out.
Is it possible to monitor the calibration when the pre-run script is running?
How can I debug it when I am having error?

The measurement expressions here are error free because I used it during calibration using multiple tests and calcVal.
I am trying to use pre-run hoping to make the flow simpler.

The error message:

The code:

;Use let() to avoid creating global variables
(let (CODE_CHOSEN, TRAN_TOT)

;Debug printf statements are written to the Job log

printf("pre run: Hello World!\n")

;Initialize and inherit the test setup from the current point
