The EBMS Excel 
 add-in tool is a powerful way to access EBMS but often requires nested 
 functions.    An error within this process because of various 
 errors can be difficult to identify.  The Error 
 log is a powerful tool that can assist the user in identifying 
 wrong parameters, syntax errors, typos, and a host of other issues.    The 
 error log will display technical errors that would normally appear as 
 an error message within EBMS as shown below:

The Errors pane will show on the right side of the Excel spreadsheet as shown above. Note that the errors identified by #VALUE has limited details but the error log displays more details.
NOTE: Close all applications and other Excel spreadsheets if the Errors pane does not show.
