I am using Excel 2007 for Windows.

Excel complains that one of the functions in the following formula has too
many arguments. I am not quite sure which function is the problem... Any
suggestions on how to fix this?
Thanks.

=if(m4="IT1P",if(or(or(t4=40,n4="KAN"),and(t4=52,r 40)),ac$6/5*7+ad$6/5*7+ae$6/5*7+af$6+ag$6,if(t4=52,if(q4="E",ac$6/5*7+ad$6/5*7+s4+ae$6/5*7+af$6+ag$6,if(q4="F",ac$6/5*7+ad$6/5*7+o4+p4/5*7+ae$6/5*7+af$6+ag$6,"N/A")),"N/A"),"N/A"),if(m4="IT1L",if(or(n4="ACQ",n4="ERM",n4="MOF", n4="MOR",n4="PRO",r40),ac$4/5*7+ad$4/5*7+ae$4/5*7+af$4+ag$4,if(q4="E",ac$4/5*7+ad$4/5*7+s4+ae$4/5*7+af$4+ag$4,if(q4="F",ac$4/5*7+ad$4/5*7+o4+p4/5*7+ae$4/5*7+af$6+ag$6,"N/A"))),”N/A”),"N/A”)
