Referring to sheets in formulas
 

Hi,
I have the following formula set up which refers to one other sheet:

=IF(ISERROR(SMALL(IF(('MANAGEMENT POLICIES &
ADMIN'!$E$10:$E$128="Yes"),ROW($C$1:$C$119)),ROW()-ROW($C$1))),"",INDEX('MANAGEMENT
POLICIES & ADMIN'!B$10:B$128,SMALL(IF(('MANAGEMENT POLICIES &
ADMIN'!$E$10:$E$128="Yes"),ROW($C$1:$C$119)),ROW()-ROW($C$1))))

How can I add to the 'MANAGEMENT POLICIES & ADMIN'! part of the formula to
work for sheets 2,3 and 4 too.
