Is there a limit to the number of parentheses you can put into one cell in
excell's spreadsheet?
For instance, I try to enter:

=if(d4=1,offset(data!c24,0,0),if(d4=2,offset(data! d24,0,0),if(d4=3,offset(data!e24,0,0),
if(d4=4,offset(data!f24,0,0),if(d4=5,offset(data!c 43,0,0),if(d4=6,offset(data!d43,0,0),if(d4=7,offse t(data!e43,0,0),if(d4=8,offset(data!f43,0,0),if(D4 =9,Offset(data!c62,0,0),if(d4=10,offset(data!d62,0 ,0),if(d4=11,Offset(data!e62,0,0),if(d4=12,offset( data!f62,0,0),""))))))))))))

but excel won't let the function through, saying that there is an "error"
after the d4=7 part. If you know of any such limit, or a better and more
efficient way to go about what I'm doing, it would be much appreciated.
Thanks in advance.
