Buy Now Button Not Working

[SeanDobra]

Hey 🙂 
Any help would be really, really appreciated!
All of my Pay Pal "Buy Now" Buttons on my wordpress website simply send my website viewers to the paypal log in page. Not to a page where they can purchase the item. 
Here is an example of one of the buttons code:
html - <form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top"><input name="hosted_button_id" type="hidden" value="Y5L9FKD89UY3L" />
<a href="https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&amp;hosted_button_id=Y5L9FKD89UY3L"><input alt="PayPal – The safer, easier way to pay online!" name="submit" src="https://www.paypalobjects.com/en_AU/i/btn/btn_paynow_LG.gif" type="image" /></a>
<img src="https://www.paypalobjects.com/en_AU/i/scr/pixel.gif" alt="" width="1" height="1" border="0" /></form>
email - https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=Y5L9FKD89UY3L

Here is the link to the page on my website where the above button is listed - https://starmaxfilms.com/cameras_and_drones/
We are looking at the Sony FS7 Camera Kit Day Rate Pay Now Button. 

Thanking you so much in advance!
