Hello...I need help with a piece of VBA code that will automatic run one of my Macro (macro name is 'Update_Chart' when workbook is open. Not sure if you need to know the workbook name but it will always start with 'Sales Forecast'..then followed by Month and Year. So, in this case, this will be 'Sales Forecast October 2008.xls'. I appreciate your help with this. Thank you.
