No arguments for rule sets

Hi guys i'm writing u for a question, i've installed your verison 2.x because i need the power of rules.

Basically i need to load a content profile when a private message is sent and perform a check if a cck field has a predefinid value.

My goal is: Every person who join the site and sets his cck Place on London (select list) when a PM is sended to him, he can recieve a sistem mail .

But when i was trying to add a new rule set I discovered there is no Private Message arguments.

I will represent my steps:

First time I tryed to create a triggered rule:

1 Called send mails:

2 Selected Event: A mesage is sent

3 Added Load user account
--> on user uid used the token [recipient:uid]
4 Load a user Profile
--> User, whose profile should be loaded: Loaded User
-->Content Profile Content Type: User Profile

Perfect, but now i need to perform a a condition if a cck field has a value.
Impossible to do with a single triggered rule

So i need to do a rule set that do this job

I'm gone to Rule Sets

Created a new rule set called pm_notice

Inside the rul set added two rules called:

grab_data

in CONDITION: leaved empty

in DO:
Load a user account
Load a user profile

and another rule called

verify_data

in CONDITION: CCK field has value
(for example verify the user lives in London)
i select my cck (is a select list) -> field_place, and value is london

DO

Send a mail to a user

Actually I can't do this because i can't load an argument of privatemessage when I create the new rule set.

And when I select the trigger A message is sent in DO I can't select Rules Sets.

Someone can help me ?
Thx in advance
