Single Cell Drop Down to Determine Data Sheet Lookup

Hi again,

Something else seems strange to me - the Usage-Cost Detail worksheet contains 78 rows of data (i.e. non Total / Subtotal rows), but a monthly worksheet contains only 76 rows of data. Where do the two extra rows of data come from?

Also, in Rows (53:81) of the Usage-Cost Detail worksheet, is there a reason for the data row sequence being different from that of the monthly worksheet, or can the same sequence be used?

Regards,

Greg M
