PAYPAL BuyNow Button

PAYPAL BuyNow Button

  
Since Paypal module is outdated, I'm searching a way to put a simple Paypal BuyNow button in my page.
I created the button in my paypal account and I have the code. Now, the question is: how can I put the button in a webscreen of my app?
Hi Mara,
The code you have is probably some html, my suggestion is that you use an expression and paste the code into it, but change the property "Escape Content" to No.
I did that and the button appears.
But there is a problem.

The page itself is a form.
The paypal button is inside a form.
So, the button does not work.
When I check the page html code in Firefox, the statement "<form action='https://www.paypal.com/cgi-bin/webscr' method='post' target='_top'>" is in red color and there is an information: "Nasted forms not allowed".

So, I still have a problem.
