add columns to spreadsheet

[Peter083]

Hi,my question is as follows. If I have the number of months in a worksheet e.g. in cell B3 the number 9, commencing from a certain month say January 2010 in cell B4, and I want to do a cash flow on a separate worksheet for this period, is there a quick way that I can get the separate worksheet to show only 9 months, and if possible to show the actual months commencing from January 2010 ? Any help will be much appreciated.
