Can't use Tsukihime's conditional effects

[BlackLiquidSorrow]

Okay so I'm trying to make a buff that restores hp when a certain armor is equipped but whenever I use it I get this error script effect conditions line 128: SyntaxError occured unexpected $end.
My effect formula is
<effect condition: 2>
a.hp > 1 ?
</effect condition>

Tsukihime's script is here https://forums.rpgmakerweb.com/index.php?threads/conditional-effects.25063/
