Create a string value called "DoLevelSelect" and set the value to '1'.

Now, create 19 string values titled "LevelSelect#" where the number sign "#" is replaced with the numbers 1 through 19. Each of those string values will be assigned a value that corresponds with each level. To get these values, open the Game folder and go to datalevels. Put the name of each file (do not include the '.dll") you see there as the value for each of the LevelSelect# entries.
