VLOOKUP Formulas stopped working

Hi!  I have two files that are linked.  They are linked with a VLOOKUP formula.  They have been working until this week.

I'm trying to find the reason the VLOOKUP formula doesn't work anymore.  When I enter information or numbers on the supporting file, it's supposed to automatically fill in the corresponding cells on the linked main file.  But that doesn't happen anymore.  Now, when I enter the numbers in the supporting file, nothing shows up on the main file.  It's almost as if they are not linked anymore.  How do I troubleshoot the problem and correct the linked files? 

Thank you!

    Hi TRichardson35 

     

    I assume, that both files are open, right? If yes, and if the VLOOKUP does not work, could you check if the workbook calculation mode is switched to manual?

    Usually, this should be set to "Automatic"
