There's no point in having a script as u can simply click the itemname to get sent to the history.

Also what you're trying in Post #5 is ingame, the guide is for profiles, not ingame

Thanks for that clarification about that old guide being for profiles and not in game.

I am noob and didn't know how to check how much I paid for some items.i wanted to check price history, and thanks to light prince I found out I can check the price history when items are in my profile. I'm all good now!

I think maybe waaaay back in the day you used to have to use developer tools to check the item history, but now when I highlight over an item in my profile I can just open the link to check history. Maybe you couldn't do that back in the day, idk...

But my question has been answered. Super easy to see item history. That's all I needed to know how to do I just didn't know how to do it bc I'm a noob
