Excel question

Hello,
I am trying to create a form based on the last row of information on a separate worksheet. I would like for this form to automatically update once new information is entered and the last row has changed.

For example say i have a spreadsheet with 20 rows of data, I want the form to pull data from row 20. When I enter data in row 21 I would like for the form to automatically update with data from row 21.
