Can Not verify DKIM to enom.com

Hi, I have been trying several days now to try to verify my DKIM to enom.com everything seems to be correct but every time I try to verify it keeps saying Verification Failed. I have the correct domain and selector, and I change the record value in zoho and my domain site and wait even a couple days to try to verify and it still fails, please help. domain nwcarcollectibles.com and selector zoho._domainkey.nwcarcollectibles.com

Thanks.
