Wfuzz Issues while bruteforcing

Hi guys I’m having trouble with wfuzz.
I’m trying to bruteforce this vulnerable web application and yet no password and username is discovered it scans my custom payload though and yet nothing else is discovered take a look

This is the command i used:
wfuzz -c -z file, -z file, -d “uid=FUZZ&passw=FUZ2Z” --hc 200

Any body wants to tell me what is the problem??
