Rick,

Try this.

I want to sum a column from a different sheet using the date as the condition
for the formula. I need a formula that will sum all the amounts that are
equal to or less than a specific cell E1 (which would be the date). Store 1
is the first sheet and I have 99 sheets for 99 stores. I tried the following
formula but got back -3.0559E-10 as the result. The result should have been
$18,810.90. I am not sure what I am doing wrong. Any help will be greatly
appreciated.

=SUM(IF(('Store #1'!B1:B73<=E1),'Store #1'!E1:E73))
