Lookup
You already connected the contact to the deal, now you can create a lookup field to get the contact’s phone number or any other details and display it under the deal’s record without the need to duplicate the data in 2 places.
Creating a Lookup field
  - To be able to use a Lookup you should have
 
  
    - A Linked List field in the same list
 
    - The linked should only link to one record at a time (Allow multiple should be disabled)
 
  
  - Under any list click on fields
 
  - Click + Create New Field
 
  - Type in a field name
 
  - From “Field Type” Drop Down List select “Look Up”
 
  
    - Next you will select the Linked List you’d like to Look Up according to
 
    - Then you will select the field from the linked list that you’d like displayed on the current list.
 
  
  - You’re good to go!

  - Under the list look for the “Lead Owner” field, you will notice the following:
 
  
    - The field is of type Look Up
 
    - It’s looking for the value of the Lead’s Owner under Contacts List
 
    - This will help better calculate how many of the leads generated by that person end up as closed deals.
