The app (https://x.thunkable.com/copy/267f702afa53f3e558d6873e8bd5419c) is suposed to generate a graph but the only thing that its doing is opening a new tab that its empty.Would you mind telling me what am i doing wrong.
You have to put a https://… and not a html and all that what you put in… so you have make your own website on webflow or squarespace or wix your choice and style it there and than put your link into the app
Thats not the solution, i have made a mistake in the html code ,which is correted now and everything works.
Cool 
good to know that it possible to do that
