    Dear JYC987654321,

    That may be somewhat true. However, there are amazing exceptions. If you post questions to the MrExcel web site Discussion Board, there are people there that are incredible at both!

    Give it a try.

    I noticed that people who are really good with formulas and reports are not as versitle with macros. Also, I seen people who are experts in VBA that sucks with formulas.

    Anyways, thanks for your help. I’ll join your website soon. I’m always eager to learn more excel.

    Thanks,
    JYC

    Dear JYC987654321,

    As I have said in other comments, I can hack my way through Macros and VBA, but I am not as good with that as I am with the Excel Surface (formulas, data analysis, Charts). I feel comfortable teach the surface stuff but not the Macro/VBA stuff. I have made a few videos on Macros. Search my site for Macros.

    I’m trying to write a macro that selects the last item in a dropdown menu of a pivot table.

    ex:

    DATE (dropdown menu)
    6/1/08
    6/2/08
    6/3/08

    I need a macro that selects the last date from the dropdown menu.

    Can you please help?

    Are you good with macros by any chance?
