can I do this in excel

[bee]

I have the following columns in a worksheet
A B C D E
DATE ITEM COST TAX TOTAL COST
28/04/07 LAYING PIPE $50.00 $5.00 $55.00
THROUGH TO
6/5/07 LAYING PIPE $50.00 $5.00 $55.00

can excel calculate the total cost for any period for example say from
28/04/07 to 06/05/07. I have treid sumif and vlookup but cannot get a formula
to calculate between the dates specified.
Is there a formula that I could use to calculate from and to or between dates.
thank you for your advice.

=SUMPRODUCT(--(A2:A20>=--"2007-04-28"),--(A2:A20<=--"2007-05-06"),E2:E20)

Yes it can, Try:-

=SUMPRODUCT(--(A1:A5>=DATEVALUE("20/04/07")),--(A1:A5<=DATEVALUE("05/06/07")),D15)

Thank you very much for your reply.

Could you tell me what the (-- means in the formula.
I appreciate your solution to my problem.

The -- converts a TRUE/FALSE condition into a numeric 1/0 which allows
SUMPRODUCT to perform its calculations.

See this site for an excellent overview/explanation of SUMPRODUCT:
