Anyone here proficient with Lua?

I’m using a couple of Lua scripts on my MiCasaVerde Vera Plus that someone else wrote and I need to find a way to incorporate the duration payload for the scene function of the HTTP API. The script author has mysteriously disappeared.
I’d like to know if there is anyone here that would be willing to do me a favor and take a look at a fairly simple Lua script to see if there is a way to add the ability to change scenes over a specified period of time, as detailed in the HTTP API documentation. I looked at the script and it seems fairly simple, but my Lua skills are not up to par for the task.
Thanks in advance!

Still looking for help on this. Anyone???
I’d really love to finish this project!
