Hello,

I am designing an experiment in which participants can either earn money (incentive) or lose money (decentive) for correct guess per trial. For example, if it's an incentive block, participants will earn $.15 for each correct guess per trial within that block. But if the next block is a decentive block, they will lose $.05 for each correct guess.

I'm using the counter element so that participants can keep track of their earnings. However, currently, as I've programmed the experiment, if participants lose money below $0, the program records negative numbers, but their counter amount shows $0. So, when participants start earning money again, they need to get out of the negative range before the counter will show anything over $0.

Basically, I need to know how to get the counter to reset the participant's earnings to 0 when they dip into the negative digits (we are not interested in having participants owe money for this task). Would I do this using the reset interval attribute? Or would I need to fix something elsewhere in the code, outside the counter element?

Please let me know if you'd like to see my code. Thank you!
