Hi

You would need to have the buton as a control on a form not a query.  Set
the OnClick event to open your fom (as a popup) and filter it open at the
record you want to add the data to - you could select the student  from a
combo box of list.  Not as long as the primary field of the tudent table is
the bound column of the combo your could set the column width the 0 so you
would just be able to see the name.  If you you set the auto expand to yes
this would assist you if you have a large number of students.
