Logging messages for all users in OG

Hi,

I want to log message for all users in organic groups.

I create a rule -

Event: After saving new content

Action:

• Get group members
• Loop through all members and log the message for each user.

After the action - the same message should be logged in for each user in the organic group.
But the message is logged only once (only for the first user in the group).

Thanks in advance.
