What is wrong with my code? Variables are not behaving.

Question

First passage:

(if: $Lives is -1)[(show: [[Death]])]
(set: $Ra to (random: 1,99)) (set: $Rb to (random: 1,99))
*Wise Woman*: Very well, what's $Ra minus $Rb?

[[Answer -> Answer 2]]
---

''(print: $lives) Lives Left''
''(print: $coins) Coins''

-_>''Inventory''<_-

(print: $inventory)

Second Passage

(set: _Answer to (prompt: "You answer:", ""))
(if: _Answer is $Ra - $Rb)[(show: "[[Question 3]]")]
(else:)[Oh no! You lost a life! (link:"Go Back")[(show:?fan)] (set: $Lives to it - 1)]
|fan)[ [[Question 2]] ]

(if: $Lives is -1)[(show: [[Death]])]
---

''(print: $lives) Lives Left''
''(print: $coins) Coins''

-_>''Inventory''<_-

(print: $inventory)

What's my problem?

Answer 1

(set: _Answer to (prompt: "You answer:", ""))
(if: _Answer is $Ra - $Rb)[(show: "[[Question 3]]")]
(else:)[(set: $Lives to it - 1)Oh no! You lost a life! (if: $Lives is -1)[(linkgoto: "You died.", "Death")](else:)[(linkgoto: "Continue", "Question 2")]]

I changed the second passage to this^ and it worked for me. Also maybe this in the first passage, the 'goto' instead of the 'show' macro: 

(if: $Lives is -1)[(goto: "Death")]

I think the problem was with the setup of your if/else macros.
