Me again

. Can anyone tell me what I'm doing wrong with a certain command?
I succeed with deleting a specific file from a list by looping file-by-file through the folder, and using the "If $FileName$ Includes" command, followed by "then delete files $Filename$.$Extension." In the "If Variable" window, my operator is "Includes," and I entered a a single letter that only appears in one filename into the "Fix" window. Works like a charm.
HOWEVER, I can't figure out how make it work with multiple parameters. I have tried creating a list variable with a couple of entries in it that occur only in two of the files. But that ends up not deleting anything.
I also tried creating text file list variable, but that does the opposite, and deletes ALL the files in the folder.
I attached two AA files, one that works, and one that doesn't.
I'm sure this is something really easy, but I'm just to new at this
Can someone take mercy on me?
Thanks!
