checkbox in a column

Hi Folks
Im a math teacher and trying my hand in excel2003 VBA.
Please can someone write code to help me check students who have paid fee.
I want to use the following:

userform
Listbox1 selecting a class
Listbox2 for holding students of the selected class
checkbox When a student pays,then checkbox value is true against namein Paid? column.
Commandbutton to close userform (optional)

The default values under the Paid? columns should be False
PLEASE SEE ATTACHED SHEET BRIKA.xls . and the userform controls
The userform should show when workbook is opened and remain till its closed.
