trigger send lua script

I made a trigger as following
trigger:^( |>)*asdfjlasdfll.*
send:
AppendToNotepad("text_window","%0"..os.date("%c").."\n");
send: Sctript

the trigger is working but show the following error,

Compile error
World: xlqy
Immediate execution
[string "Trigger: mizong"]:1: unfinished string near '"<triggers>'

please help me how to correct the lua script.Thanks.

Please post the full thing:

<trigger
enabled="y"
group="normal"
make_underline="y"
match="^( |&gt;)*【密宝遗踪】玄武神帝：.*"
name="mizong"
regexp="y"
send_to="12"
sequence="100"
>
<send>AppendToNotepad("mizong","%0"..os.date().."\n");</send>
</trigger>

The trigger works well, but the script doesn't run, show the error message.

In the "send to script" box a \n is turned into a newline, before it even reaches Lua.

To have it reach Lua double it like this: \\n

Thanks a lot
