Collecting Data from other Form Entries

Hello, I think this will be easier for you guys, I have three forms created. Here are the details
I created 3 forms..
1. Client Details
2. Magazine Subscription
3. Book Sales

for the magazine subscription and book sales, I added one field and named it as "Client ID" which means that subscription/booksales is for the client that owns the inputted ID. Now what I want is to relate them to each other, on thing I'm trying to accomplish is when viewing the entries of Client Details I want to include there their Magazine Subscription and Booksales. I noticed that when I click "edit" on the upper right of the table when viewing all the entries there is somethin popping up on the screen where can I drag a column I wanted to add, Is there a way to use that and a column from other form entries or if not, how can I relate those forms to each other? thanks,. :)

How hard to reply "Yes we can do that" or "No we can't". So that i don't have to wait because my time is running down. If you don't know then Its not a problem, I just don't want to purchase Ninja or Formidable form while i'm still waiting for your reply because i'm not sure if you have a solution or nothing.
