Error "cannot find symbol"

hello, I am new to java programming and im trying to do a "do while" loop in this program. However it gives me an error "cannot find symbol" I dont understand what I am doing wrong, because i tried using the variable transactions the same way using just a while loop and it worked just fine. Please any help?

JAVA Code:

do
     {
         Scanner tran = new Scanner (System.in);
     
        System.out.println("How Many Transactions would you like to do in Month: " + count + " (Entering a negative number will terminate the program)");
     
     int transactions = tran.nextInt();
     
        for (int insideCount = 1; insideCount <= transactions; insideCount++)
        {
            Scanner checkTran = new Scanner (System.in);
            System.out.println("Please, Transacion #" + insideCount + "(A negative number will result in a withdrawal");
            double amount = checkTran.nextDouble();

            if (amount > 0)
            {
                testAccount.setDeposit(amount);
            }
            else if (amount < 0)
            {
                testAccount.setWithdrawal(amount);
            }
            
        }
     
            
     } while (transactions > 0); //here is the error
     } 
     }

The problem is that the variable transactions is outside the scope of the while() comparison because you declared the transactions variable inside the do{} statement. Try this:

JAVA Code:

System.out.println("How Many Transactions would you like to do in Month: " + count + " (Entering a negative number will terminate the program)");
Scanner tran = new Scanner (System.in);
int transactions = tran.nextInt();
do
{
   for (int insideCount = 1; insideCount <= transactions; insideCount++)
   {
      Scanner checkTran = new Scanner (System.in);
      System.out.println("Please, Transacion #" + insideCount + "(A negative number will result in a withdrawal");
      double amount = checkTran.nextDouble();

      if (amount > 0)
      {
         testAccount.setDeposit(amount);
      }
      else if (amount < 0)
      {
         testAccount.setWithdrawal(amount);
      }
            
   }
} while (transactions > 0);

No problem. Remember the scope of your variables.
