Javascript & HTML carry information over between question blocks

Question

Hello, I’m currently working on an n-back task (both 2 and 3 back). For practice trials, I want there to be feedback, that displays when the participant correctly/incorrectly identifies a match.When clicking preview question/block, everything works as intended. However, when I preview the entire survey (multiple trials are shown after each other), only the first practice trial shows the right feedback. The other blocks are able to identify correct matches and responds to input, but it will only briefly flash “Correct” before switching to “Incorrect”. It does not matter if there are other, not practice trials in-between, the issue always occurs. I assume something is carrying over to the next question, but I’m not sure how to fix that, since I don’t have much experience coding (this is also why my code is pretty messy and probably not correctly implemented...): N-Back Task

N-Back Task

Please read the instructions carefully!
In the following task, you will be presented with a sequence of letters. You will only see one letter at a time, so try to remember the previous ones as best as possible. Press 'm' on your keyboard if the current letter is the same as the letter presented 2 steps before.

Here is an example:
A B X C X

In this case, you would have to press 'm' on the second appearance of the letter 'X'. You can now practice this task once. If a letter flashes, it means it is shown for a second time. These letters still count towards the sequence. It is also possible, that there is no match in a trial. Do not be alarmed by this.
Please note that in the real experiment, you will not be able to see if your answer was correct.

This was the practice trial. From now on, there will be no more feedback.

Hi! I apologize, as I don’t have a response to your question. But I am trying to also program an N-back task with little luck. Have you been able to do so effectively?
