Skill question

Alright so i been wz editing some skills and i ran into a problem that i have never seen before

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 3 >= 3
        at java.util.Vector.elementAt(Unknown Source)
        at tools.CaltechEval.reduceTokens(CaltechEval.java:476)
        at tools.CaltechEval.eval(CaltechEval.java:325)
        at tools.CaltechEval.evaluate(CaltechEval.java:146)
        at server.MapleStatEffect.parseEval(MapleStatEffect.java:120)
        at server.MapleStatEffect.loadFromData(MapleStatEffect.java:412)
        at server.MapleStatEffect.loadSkillEffectFromData(MapleStatEffect.java:8
6)
        at client.Skill.loadFromData(Skill.java:292)
        at client.SkillFactory.load(SkillFactory.java:77)
        at server.Start.run(Start.java:75)
        at server.Start.main(Start.java:125)

I would appreciated if someone can give me some hints or ideas on to what could be causing this. This only happens when i dump some of my edited skills into the wz folder
