Phil, welcome.
The cuttings in the fridge will last, but you should melt some candle wax on the cut ends, and store them without paper towels or any kind of moisture.
Some times things just go wrong. It's part of the process.
Next time you get cuttings, give them a 10% bleach scrubbing with an old toothbrush, let them air dry completely, then wax the ends and store them in the crisper for a couple of weeks.
When you're ready to start again, take some sphagnum moss and soak it for 20 minutes.
Get an airtight plastic container, and grab handfuls of wet sphagnum, squeeze as much water out of each handful as you can!
Take those compressed balls of sphagnum and fluff it, loosen the fibers.
In your plastic container, lay out half of the sphagnum.
Give your cuttings a fresh cut, give them a scrape or three across that bottom node, until you see green. Lay the cutting in the bed of sphagnum, all lying in the same direction, and not touching. Fluff up the other half of the sphagnum, and sprinkle it on the cuttings, making sure you cover them completely.
Check on them by pulling the sphagnum away from the tip side, not the root side. The roots will be stringy and fragile.
If you're not someone with a gentle touch, you can corkscrew rooting cubes into the cuttings before laying them in the moss. This protects the roots. The rooting cubes should also be squeezed of all water.
When you have the water level just right, the moss doesn't look shiny, and it should be aromatic when you open the container.
If at some point during the process the moss gets crispy or lighter in color, pull the cuttings and repeat the process of wetting and squeezing it.
The most important thing is to be patient (this way takes about 1 month), and really squeeze all the water out of the sphagnum.
Just remember that the cuttings need humidity, not water.
They will only start to need water when there is a bundle of roots the size of your hand, and they have new growth one or two inches long, with a couple of leaves on it.
When you're up potting, mix the water into your medium and (you guessed it) squeeze all the water out of that, fluff the soil, place the cutting, and don't water.
It'll be another 3 weeks, if kept in humidity, before the cuttings need a spray of water. If you dig down an inch into the potting soil and it's still dark (moist), it's not time.
Just don't get expensive cuttings to start out. There's a good amount of heartbreak in the beginning.
Armando offered some cuttings. I do too.
PM me when you're ready to start again.
