[Help] Creating some cards

Hello!
I'm creating my own custom pack for DotP 2012, so i can use my real vintage squirrel deck in the game.
But i'm having problems with some cards, and i'd like u guys to help me if it's possible.
By now the 2 cards that i'm having trouble are Squirrel Nest and Earthcraft. Together they form a powerfull combo.
Squirrel Nest made it enchant the land, but i can't make the enchanted land tap for the effect. By now i could only make the enchant tap.
And in Earthcraft, i can't even use the ability. I've put an actvation ability, but i cant use or cick in it during the game.
If someone knows how i can make these cards' abilities please tell me.
