How can I make sure a link will not change in a file. I have a file that that links information from a sheet in workbook. For example, Class sheet is where I input all of my entry data. When I input the data in the Class sheet it inputs the info in the Matrix1 sheet. But I have noticed that when I copy the file to a new folder or I take from home to my office computer it changes the links and breaks them or don't transfer. How can I avoid that?
