hello, I am making a function that deposits money to accounts, the function works perfectly fine, it just has a small problem.

when adding the amount of money the user entered to the actual balance in the account, the function updates only the first balance(adam's balance)

for example, when I am depositing money into another account it does not update the actual balance in the account.

I want to know where is my problem exactly and how to solve it

thanks
