Hi Suzanne. Can you share pictures of the cut end so we can get a look at the callous? Depending on the variety, it's not unreasonable to take longer than 40 to 50 days and shrivel in the process. If you want to try and plump them up, make sure you use rain water. Any chlorinated tap water will kill plant material and cause rot. Otherwise, just keep it warm like you have been doing and be patient. I have had some take many months to root. I dont know what the weather is like there, but where I am it is very hard to root anything this time of year. Vigor is coming to an end which a vigorous actively growing mother plant is necessary for fast rooting.

Thanks Chris for the advice. I will put up a couple of shots of the stems Good to know about the chlorine as our water is chlorinated these days. We do try to make sure that any water is sitting to allow the chlorine to dissipate. Not 100% sure about variety - don't think it is anything special . It is spring here. I live in Christchurch, South Island so we can still get frosts but the cuttings are kept inside.

It looks like you have a decent callous going. I would just pot them back up in slightly moist soil and keep them warm. No direct sunlight, no watering. Just wait till you start getting some leaves and you will be good to go! A tip, pot them up in small pots, maybe quart size.
