Dynamically update the worksheet value

Hi!

I have different worksheets which are link together to automatically update values. These worksheets are in a folder as shown in my code. Now I want to reuse the worksheets, so I copied the worksheets and put them in another folder named "2019-2020". I then proceeded deleting the values of the worksheets except the formulas. I found out that the formulas does not dynamically changed the reference. What should I do so that whenever I want to reuse my worksheets, I will no longer change my formula, it will just dynamically change. Is this possible in excel?
