Ok, lets see if I can explain this correctly. I have several workbooks that "feed" from main workbook. In this main workbook, I have several tables and named ranges. In order for my "daughter" workbooks to operate correctly, the main workbook needs to be open (which I can deal with). My question is...is there anyway to make the main workbook automatically open in the background whenever I open up any of the daughter workbooks? Currently I have a hyperlink set up in each daughter workbook that I click on to open the main book, and then minimize it before I can process any information through. I would be happy with having the main book open whenever I open excel, I just want to know if I can get it to open in the background instead of having to open it then minimize it every time! Any ideas or suggestions?
