To help gain more insight into your problem, I recommend liberally sprinkling Debug.Log() statements through your code to display information in realtime.

Doing this should help you answer these types of questions:

  • is this code even running? which parts are running? how often does it run?
  • what are the values of the variables involved? Are they initialized?

Knowing this information will help you reason about the behavior you are seeing.

I assure you the person best positioned to solve this is you, by the steps outlined above.

If you are unwilling to do the engineering, I’m sorry, I cannot do it for you.
