Hi,

I have two tables that each have 2 columns. The first column in the first
table is composed of dates that are in ascending order, but have some
duplicate dates and missing dates. The second column has numbered values. The
first column in the second a table is all dates 1/1/08 to present. I want the
second column to be an output of a function. The first part of the function
is easy and would find a date in the first table and return the corresponding
column 2 value. The tricky part is that when there are two dates, or more
than one, then I want the output be the sum of the column 2 values. Does this
make sense? Thanks for your help.

John
