Checkbox variable

Hello folks

I'm kinda new on the "programming world" and i'm having some trouble.. I want to make the variables in the checkboxes show up but I can't find the tutorial to do this (I'm using Harlowee Macros)... Basically I want that the game tells the player wich checkbox he or she didn't checked ( he/she needs to complete all the tasks, if not the game have to redirect the player to another passage saiyng wich tasks he didn't complete). Can anyone help me?

ps: english isn't my mother language so i dunno if I made myself clear
kek.
