Larry,
Did you use quotes round the "Y"?

I need some help on the following formula. It works
perfectly as written. I want to replace the reference
to "P4=30" & "P4=59" with a new column that if tagged
with a "Y"
(S4=Y), that the formula will work as composed.

When I replace the reference as staed above with the new
column, the figures do not compute properly.

In order to understand what I am trying to accomplish, I
will probably have to send a copy of my spreadsheet for
explanation.



=IF(ISBLANK(A4),"",PRODUCT(H3<N3,D4=H3,P4<=30,INT (A4+E4*
(P4<30)+F4*(P4=30)-A3-I3-(I3<E3))*8/24+MAX((A4+E4*(P4<30)
+F4*(P4=30)-A3-I3-(I3<E3))-INT(A4+E4*(P4<30)+F4*(P4=30)-
A3-I3-(I3<E3))-16/24,0))+PRODUCT(H3<N3,D4=H3,P430,
(A4+E4*(P4<59)+F4*(P4=59)-A3-I3-(I3<E3))-16/24))
