I am using concatenate to create a link to a cell in a different spreadsheet.
I cannot find an easy way to activate the link.

I have a formula =("="&F$1&"!"&"$B"&$A60) where the content of strings and
referenced cells generates a string: =filename.xls!$B67

However I can't get it to display the value of the string. It just displays:
=filename.xls!$B67


If I copy the cell and paste as a value, I'm close, but to get it to work as
link, I have to edit the string...for example replace "=file" with "file"
and then replace "file" back to "=file" and then it works correctly. Is
there a better way to activate a link?
