How do you sync info from a form into sub forms in individual records?

I have created a form where I can keep track of individual client records, their contact information, etc.  I have also created a separate form where I can input client hours and services each time they visit the office.  I would like to add this second form into each clients personal record form.  I added it as a subform however this doesn't' sync the information added to this new form.

Each time an existing client comes into the office I want to be able to add their name, the date, and the services they received into my second form (client tracker form).  Then I want this second form to be a link to the personal records form so that when I click on their personal records form ALL the entrees made in this second form for this personal will appear.

Is this possible?
