proper format: to use salt file

I'm trying to crack a sha256(pass.salt) and I don't know the pass or the salt, but I do have two separate files, one that contains the pass and one that contains the salt(not too big). I just can't seem to get it right (getting error)... This is what I'm currently trying:

hashcat -m 1410 [hash.file] [pass.file] -e [salt.file]


Can someone please tell me what I'm doing wrong.
