what's wrong with this formula

[Duncan]

I am using this formula
=SUMIF(Programme!E$3:E$3700,"<J2",Programme!F$3:F$3700)

J2 is a date selected from a drop-down list using validation/list
On the Programme tab column E also contains dates, column F contains
numbers.

I want the numbers in column F to be summed, if the date in column E
is earlier than the date on J2

Have I explained that clearly?
It's just not working.
Any suggestions would be most welcome
thank you

Hi Duncan

Change it to
=SUMIF(Programme!E$3:E$3700,"<"&J2,Programme!F$3:F$3700)

With the J7 within quotes, it was looking literally for <J2

Try it like this:

=SUMIF(Programme!E$3:E$3700,"<"&J2,Programme!F$3:F$3700)
