Hello, this is my situation. I have two workbooks "A" and "D". I have to copy from A to D a certain ammount of info. Now A is always the same file so i can use the workbook's name to refere to, but D is always changing. Any ideea how i can refere to it, tried to do it by index but couldnt figured it out. Only need help with how to refere to the second changeable workbook the rest works.
