I make content locker on page load, insert code to an empty page and use Iframe with the link to that page. I want to make a function like Like you see, the page has 4 step to get gift code. The content of step 2 only shows when step 1 is completed, same with step 3 and 4. So I want to know how to do that ( And in step 2 has offers people need to do, how do I know when people finished the offers and step 3 show content to them) Can You have look that site and give me some advice. ( I'm noob so you guy can suggest me and I will research more) Very appreciate.
