Lua Difficult!

[GarQet]

Hello Otlanders!
I did the script to my OT but I stopped at a difficult time.
I can't do my idea, I need your help.

I got it:
local teams = {OTland, GarQet, Support, OpenTibia, Forum, OTS, Topic}
Now I need a script that drew the two names, marged them and ascribed "number" 1 and ID 1 and 2. The script must create two tables with the same NUMBER but with different names and different IDs.
ID is entered in the tebeli which is located in (System -> ID)
NAME is entered in the tebeli which is located in (System -> NAME)
NUMBER is entered in the tebeli which is located in (System -> NUMBER)
The next two names give your target NUMBER 2, and also it adds.

Example:
The script draws a GarQet and OTland.
He chose it as the first therefore assign NUMBER 1.
Picture:

Then drew two other names (The script can't draw NAMES who have already picked!): Support and Topic.
Picture:

I need this a piece of script.
PLEASE HELP ME...
Sorry for my bad English.

#EDIT
If the name was not evenly, it prints the same one.
When all names will be linked to terminate its operation.
