We've discussed this before. The screen shot, however is informative. Your values appear to be delimited by "| ". (the vertical line followed by a space.)
That we can work with using the code I posted earlier, but adjusted for different delimiter text:
If ( Not IsEmpty ( FilterValues ( Substitute ( YourTable::ColumnAField ; "| " ; ¶ ) ; "Score" ) ) ; "X" )
Will return the letter "X" if the text "Score" is in your list.
Note: there are other characters that can look like a space, but aren't, so this might still fail if the character following the | is not really a space character.
Thanks for the help again PhilModjunk. for some reason this was not working last week and I ran out of time to continue to troubleshoot this issue, but now it seems to be working fine.
Perhaps you missed the instruction in my last post to that thread: "make sure that the text used in the substitute function is exactly the text separating your values..."
