[[1.5.1][Forge 7.7.1] Make vanilla achievement 'dependant' of modded achievement]

I've been having problems with achievements. I want to make a vanilla achievement 'dependant' of mine, so the line goes from my achievement to the vanilla achievement.

 

I tried using this

AchievementList.mineWood = (new Achievement(1, "mineWood", 2, 1, Block.wood, myTestAchievement)).registerAchievement();

in my @Mod.Init but it doesn't seem to work.

 

I am using Forge 7.7.1.611.

 

Please Help!
