Add field from different module

[jayo2005]

Is it possible to add a field from a different module. I am editing the Tickets module and I want to show some fields from the Contacts module.

Add a field in the Contacts module and make a link with the Helpdesk module with code. SQL Query and php code ;)

Have you an example on how to do that. In the Contacts module I have a Start Date and an End Date field. I decided to scrap the Tickets module so I created a Custom module called Checkin. In the Checkin module I have one relatedto field to contacts. I would like to show the Start date and end date from Contatcs in the Checkin module.
