For example
In A1 I have the text: C:\File\[workbook.xls]worksheet
In B4 I want the result to be the value of cell C10 from the file referenced in A1.
However, I need the workbook to be closed. The file location changes every month, which is why I want to be able to change the file location in one cell and all of my formulas reflect that. I'm open to any suggestions (VBA, Macros, etc).
