You can't use whole column. You have specify a range (eg. B2:B65000)
Don't forget ctrl+shift+enter, not just enter

Hi

I have a formula:

=SUM(IF('Jan 08'!$B:$B="Day",IF('Jan 08'!$E:$E=A3,'Jan 08'!F:F,0),0))

and this is returning me a value of 0 when it should be 2. Is there a
way I can see step by step what Excel is calculating for each part of
my statement to see what it is doing?

Cheers
