data entered in each coloumns of one sheet to be extracted with r.
 

i am entering all the information based on top of each column names. for
example if entering students marks details in each columns headed in all
subjects with student's name in one sheet, then in the second sheet, I need
extraction of one student's details with reference to student's name. If
scroll down one student,s name, then that sheet should display details of the
students.
