Fixing and Tweaking a formula

[asad]

Hello Guys,

I got the following sheet and formula in there:

Excel Workbook
	A	B	C	D	E	F	G	H	I	J	K	L	M	N	O	P
1				RDO As On	RDO As On
2				30/03/2011	15/05/2011		13/03/2011	20/03/2011	27/03/2011	3/04/2011	10/04/2011	17/04/2011	24/04/2011	1/05/2011	8/05/2011	15/05/2011
3	DF064	ADDERLY	ADDERLY, David Allan	40:00:00	54:00:00										0
4	DF002	ADDICOTT	ADDICOTT, Steven Charles	20:00:00	34:00:00										0
5	DF078	AGGETT	AGGETT, Brian Charles	30:00:00	44:00:00										4
6	DF129	AKHTAR	AKHTAR, Tahir Mamhood	15:00:00	29:00:00										0
RDO

But, the formula in O3 won't work without opening the other file. Is there any way I can make the formula get the result without opening the file?
And is there a better and shorter formula to do the same job?
