Macro to hide colums

[mohk123]

Hi Everyone,

I want a macro that will automatically create columns based on the project start date and end date hide the columns and display only Current month (Dec 2013) + previous 1 Qtr ( Sep to Dec ) to input or to display what ever is input . This should get refreshed when I open the file.
For example in the attached test file Current month is captured in cell B5 and I would like to hide data from column F ,G & L to P and have a macro assigned to a button called Reports.

Thank for advice in advance.
