Old and new data in CB Autoactions email

Hi,
I want to send an email to the secretary of an organisation every time a member has changed his/her contact information in the CB profile. The mail should contain information on what parts of the information has changed. I know how to send the new values of the fields, but how can I include the old values and/or highlight the changed fields?

If you're using the after user update trigger then var1 is the new user object and var3 is the old user object. You can use those in substitutions to get the new and older values as follows.

[var1_cb_myfield] = New Value
[var3_cb_myfield] = Old Value
