Hello, I am using osclass on my website. I have some banners/advertise on that site. I want to change the Post button to act like this: after someone full the required fields and press the Post button to publish the item, when the button is clicked for the first time to act like it was clicked on the banner/advertise (witch is next to it) not on the button itself, and only when the Post button is clicked for the second time to publish the item. How can I do that? Thank you!
