That source code you have directed us to visit and look at is an unformatted mess.
If you want the best help, please take your code, format it using your favorite code formatting tool (FWIW, I use Visual Studio Code), and post your well-formatted code you are having trouble with, using our CODE tags, so we can examine that code without looking at lines of an "unformatted mess from 2013".
