The file I attached works on my Mac Excel 2004.

Could someone help me improve this UDF in Excel 2003 or Excel 2007 running on Windows XP and Windows Vista machines?

Many Thanks.

Hi Mike,

Thank you so much for your kind patience to help me. I've done like your guidance with new code above in Excel 2007 on Windows machine, but it seems there are still certain problems that bring no result. I don't know much VBA to solve myself.

I prefer Excel 2007 to Excel 2003, because there are enough columns in Excel 2007 to enable me to make a plan for the whole year with 365 days.

Could you please take a look at the attached file that I did and help me make it work?

Many thanks.
