Can a "lookup" be added to an IF Statment?
 

I have one row for each person for the following IF Statement to look at. Is
there a way to add a "lookup" to the IF Statement to look at a particular
person's information?

=IF('H:\Officer Automation Project\[TEMPLATE Off Mrt Summary Sheet
_04_30_09.xls]officer data'!$AV$4="y",'H:\Officer Automation
Project\[TEMPLATE Off Mrt Summary Sheet _04_30_09.xls]officer
data'!$AR$4,IF('H:\Officer Automation Project\[TEMPLATE Off Mrt Summary Sheet
_04_30_09.xls]officer data'!$BC$4="y",'H:\Officer Automation
Project\[TEMPLATE Off Mrt Summary Sheet _04_30_09.xls]officer
data'!$AY$4,IF('H:\Officer Automation Project\[TEMPLATE Off Mrt Summary Sheet
_04_30_09.xls]officer data'!$BJ$4="y",'H:\Officer Automation
Project\[TEMPLATE Off Mrt Summary Sheet _04_30_09.xls]officer
data'!$BF$4,"")))
