Setting Up & Configuring

Hi anyone have a live auction site?

Trying to set-up this auction theme as a sub-directory of my main site > https://equinecentral.com.au
By comparison this auction theme is not quite as easy to configure as one would be led to believe.

(1) Can I set the incremental bid to more than a $1 my start price is $1000 and I would like my increment @ $100

(2)Listing Days can I edit those.

I can live with (1) & (2) if the above’s not possible

The thing that is frustrating me the most is setting up the custom field “youtube”
It’s a must for me!
Can’t seem get it to work.
I have added screenshots to show.

Would appreciate any assistance on how to.
