HELP! I did not use Biz Ops in setting my audience

I followed John on the lesson on setting up the FB ad and he did not mention the Look-alike audience preference and I did not include that. My ad is not set to go live for a couple of hours. Should I delete this one and redo with Biz Ops info.

I want to get this right!

Hello Barbara - did you do any targeting in the ad? Is this in Facebook or Google?
