Motivated Go/No-Go task: Keeping Total Number Correct On Screen

I am using DirectRTv2006 software to program some of these tasks.

I am currently having significant difficulty programing/creating a "Motivated Go/No-Go" task, sometimes referred to as a "Rewarded Continuous Performance Task". Typical Go/No-Go measures require and record both go-responses and no-go or inhibitory responses. However, our Motivated Go/No-Go task presents an additional dimension. In the Motivated Go/No-go we would like to record a running tally of correct responses that is visible on the screen for the duration of the task. Essentially, for each correct response or non-response (i.e., inhibitory response), the participant is awarded $50. For each incorrect response or error, the participant loses $50. Unfortunately, we are unable to create a tab on the screen that tracks/lists the total money earned throughout the task.

Is there anyway you can explain how I can create this additional task component. Any information would be greatly appreciated.

Thanks,
