I have a parent form which is a company. It has a T-E-N-S number. 

Then I have children forms which are Mobile websites and Apps. These all have T-E-N-S numbers too. T-E-N-S numbers are a 10 digit ID which represents online assets owned by companies. I want to click on a company, and see which apps and mobile websites it has.

Here is an example

Company Form:

T-E-N-S            Company Name      Phone

1000022222      Microsoft                444-444-444

Apps Form:

Mobile Websites Form:;

How do I create a relationship between the different forms based on the T-E-N-S number? When I see Microsoft, I want to see a list of its Apps and Mobile websites     .
