Cloning problem

I'm trying to clone some plants, and they are quickly dying!

1. I'm cutting the lower branches with a razor for a clean cut.

2. I then slit the bottom and scrape a little of the sides to give the branch more contact to the clone gel.

3. Dip the end into the gel, and cover it good - Clonex.

4. Then stick the end into a wet Rapid Rooter.

5. Place the rapid rooter into an Aerogarden for light.

Wilting within a few hours, and getting worse by the minute.

Any ideas?

It's called a humidity dome... Misting with water.... And lower light by 1/4 of normal, move the light way further away after you put the dome on for the first 5 days.
