Scripting with Lua

Hi,
I am very new to Toucan-Scripting and I can´t figure out, why it is not working.

In detail I try perform several jobs with scripting. The script shall be started from a bat-file.
Everything works fine, if my script looks like this:

--Here starts the LUA-Script
sync([[c:\\temp\\quelle]], [[c:\\temp\\@dayname@]], [[Mirror]])
--...here there are many sync-jobs
--Here ends the LUA-Script

But when I want to add more options, my script wont run at all - I am about do despair!

Here is the job, followed by one of my tries for a LUA-script which doesn´t run:

[sync-1]
Source=c:\\temp\\quelle
Dest=c:\\temp\\@dayname@
Function=Mirror
CheckSize=1
CheckTime=0
CheckShort=1
CheckFull=0
TimeStamps=1
Attributes=0
IgnoreReadOnly=1
Recycle=0
PreviewChanges=0
Rules=
Type=Sync

--Here starts the LUA-Script
sync([[c:\\temp\\quelle]], [[c:\\temp\\@dayname@]], [[Mirror]], checks = "1, 0, 1, 0" , options = " 1, 0, 1, 0, 0, 0")
--...here there are many sync-jobs
--Here ends the LUA-Script

Thanx in advance for any help.
