LibreOffice - Comparing Records

LibreOffice - Phone Records on one sheet and phone Contacts on another sheet and i want to match the phone records sheets to the contact sheet. can someone just write me the formula thank you!

Hello @donpaul0110 The information provided is not enough to give you the correct answer. What is the identifier/key, which can help connect Phone Record with Phone Contact together? The best way to get help is to provide sample sheet to understand data structure and possibility to make such records connection.
