It’s pretty hard to do that. But I found a way. Use autotest to test your game with text included so you can control+F to see if the statement you put after *if varible >= 37 is in there somewhere. Another way would be to use the *bug command to test if the player can ever have that high/low of a stat at that point
*create var 0
*set var %+ 10
*set var %+ 13
*if var >= 20
*bug The Player can do this
(Then auto test it)
