Hi
I need to know how to run a formula everytime I open my workbook. There is 3 columns A1, B1 and C1. A1 have start date, B1 end date and C1 have the formula "=datedif(a1,b1,"d")".
I need this formula to run from first row until last the last row with an entry (or last row in workbook???) in it and update every "C" cell for me?
Hope I make sense?
Thank You
Gelbert
