If the original didnt die, that means its still trying to make roots. It takes a bit.
Get yourself a humidity dome and a heating mat. You can buy a combo online for about $40, and I didnt shop around for the cheapest price. Take your cuttings, bigger thicker ones the better, and shave off some of the 'skin' near the bottom where the roots will come from. Dip in a cloning solution (I use clonex), and put in your medium. Dont skimp on the cloning solution either.
Once they are in their new home just put them in your dome, mist them, and close it up. Put the entire thing on the heating mat, and turn it on. Mist once in the morning and once at night, and make sure to keep the air holes on the dome lid shut. You want it misty and humid in there. Keep them misted for a week or two and you'll have roots. Some say it can take longer though, so be patient. If they arent dead, they are doing something.
