User Form Command Button

Attached is a small sample of my workbook. When the workbook is opened only the summary page is visible. There will be over 100 records. A person clicks the record it hyperlinks to the sheet. On that page I would like a command button for the User Form I created. I'm not sure if the problem is in the User Form coding or in the coding I was using for the command button. It should be as simple as userform1.show but it's not working. I need the user form to pop open and fill in the table on the right side. Any help would be greatly appreciated.

Thank you
