Type in certain URL, Open UI image. {Input Field}

Hi! I'm trying to make a little virus game called "Extract Code."

But I need a bit of help on this one.

When the player types a certain URL, the game will open a UI image. But I want it to play a certain animation as well. When the animation completes, the UI image will open. You can exit the URL by clicking a button.

But when the player enters a wrong URL, it'll open an image (again playing the animation.) When complete, it'll give them a UI Image that explains that's a wrong URL. I really need a bit of explanation on the script and how to actually place it through. Thank you to whoever does this! :D
