Process 1 file out of multiple in Email

Hello,

  I'll start off that I don't have any issues running my process when there is only 1 attachment to the email received.  The issue I am running into is when there is more than 1 attachment in the email.  I only want to process 1/2 of the files attached.  I tried to put in the file name into the 'attachment file pattern' field not sure if I have it entered incorrectly.  
Attachment File Pattern: 'test.xlsx'

Any help would be greatly appreciated and thanks in advance.  I've posted my XML below
