Send email with objekt value

[Mariolatrie]

hi everybody,
i´m new in Lua scripting and i need a little bit of your help.
I want to generate a email, with shows me a few values of KNX objekts.
Like an coffee orderlist. 
for example:

"Message:
coffee : 5 (value of knx adress 7/7/7)
coffee with milk: 2 [b][i](value of knx adress 7/7/8)[/i][/b]
coffee with sugar: 9 [b][i](value of knx adress 7/7/9)[/i][/b]
...."

sending emails with simple Objekt values like "door open: true" does already works,
but i have a lot of ??? in my brain ´couse of this mail script.

I use a Schneider Elektric spaceLYnk HW: i.MX6 SW:2.1.1

Thank´s you a lot.

P.S.: sorry for my english, my school time is a few years ago 

greetings from Germany
