Access 2016 VBA

I have created a new database system using Access 2016. It has 4 forms and a number of tables, queries, reports, modules, macros etc. The db works well and all the facilities operate as I want them to operate. However, the app has been created by me. I am NOT a VBA programmer. I want someone to go through the existing code (about 30 pages A4) to make sure the code is correct and complete. I have sourced the code from my memory (using Access since 1992 - when it was launched), forums, MS Support, trial and error etc. I am NOT a trained programmer, but I get things to work. There is only 1 "workaround" and that is the use of DLookup. I could not get it to work, so I created my own system - it works! As I said, I want someone to check the code. I want someone in Saigon, Vietnam.
