The problem is that each time you do this

-e <"$INTERIORNAME"*.pdf>

[download]

it returns a different filename and only a single filename. You need to assign that glob to an array and then grep for the pdf extension with a regex.

By the way according to the 3rd edition of Programming Perl from 2000 this is referred to as the old way to do it. They recommend something like this:

@files = glob("*.pdf");
