This is what I always seem to get in my alerts no matter what volume name variable I use.
\ Label:APPS cc18254b
I want the ID to do away or whatever the hell that is at the end.
You can use an SQL variable to get the drive letter only. Try putting this in the email message:
${SQL:Select Substring ('${Caption}',1,3)}
That should convert 'C:\ Label:APPS cc18254b' to 'C:\'.
