After table.getn got deprected in Logitech 5.4 LUA this code doesn't seems to work anymore

After Logitech API got updated for the 5.4 Lua version, table.getn got deprected and some guys that helped me said I could update the code with # but the logic of the code doesn't seems to work anymore with this replacement, I have tried making some workaround the code but I'm not very familiar with programming, how could I fix this code for Logitech API? Could someone guide me?
