It can take up to 48 hours for a listing to appear, especially if you are a new seller.
As long as you can see it in Active Listing, all is well, it will eventually appear. Even items all listed at the same time, can appear at different times
Do not revise it, as that will send it to the back of the queue again to be indexed before it can be listed.

One more thing .
As a new seller have you fully registered with eBay's Managed Payments? All sellers have to do the following to be able to list items for sale on eBay.
You need to provide eBay with details of a bank account and have this account verified. The usual method here, is for eBay to send 2 micro deposits into that nominated bank account for you to receive, and confirm to eBay.
Once this is completed, you will be able to list items for sale, and receive payouts from those sales.
This will show you how to register for eBay's Managed Payments.
