Seeking advice ....

Today was my 3rd failure at making enchiladas. The end result looked more like lasagna after it's been assaulted with a baseball bat.

How do you keep the corn tortillas intact when rolling them up? When I tried to roll them, they crumbled into 5 or 6 pieces. The more delicately I tried to handle them the more anxious they were to crumble.

Help!
