Enter the contents of cells in a cell on the second sheet on the first available column

As I said, i have a problem with programming macro.

Lets start with example:

In the first sheet named "Form" I can manually enter values like fruit name, its weight, class etc. When I click button "Add Fruit" i want to copy that datas(range C6 to G6) on the second sheet named "Fruit". But when I add a new entry on sheet "Form" and click button "Add Fruit", I want to make new information in the sheet "Fruit" under already entered values.

To help you see figure below. I hope you understand me. I apologize for bad English.
Thank you for your help
