Multiple Logged Response and Accuracy

In my procedure, I have my participants provide two responses. The first response is about whether a target is present or absent an audio file they listen to. The second response is about whether they feel a vibration on the palm of their hand. At the end of the block, I would like to provide my participants their accuracy percentage on both of these responses (i.e., "Percent Correct (Target): __%; Percent Correct (Tactile): __%". With my in-line script of continuously adding ___.ACC to the variable name, and dividing this number by overall trial number, I am able to provide a correct accuracy percentage on the first logged response (Audio Target), but not the second logged response (Tactile event). The accuracy percentage of tactile responses is always 0%, even though I am responding correctly. I find that the second logged response is never accurate, as I flipped the presentation of which response is logged first (Tactile, Audio VS Audio, Tactile) and found that the tactile response was being correctly logged, but now the target audio response was down to 0% (the second logged response).

I am hoping to get this issue resolved, whereby I can provide my participants their percent accuracy on both of their responses, which are independent of each other but exist in the same procedure.
