You're trying to assing a negative value to the argument, regardless the
argument's value. My guess is that you may need to make the conversion
first -using sed?- and then use the resulting output as argument.

You mean you want to find for "file1.pdf", "file2.pdf", "filen.pdf"...?
Mmm, maybe you can adapt your command line for that, for instance:
alias muda='find . -name $1 -or -name $2 -mtime $3'
