I'm attempting to use subscription plans instead of recurring payments. I have 3 subscription options and would like them all on one page. If I paste the code for the first one it works fine. When I place code for the second one the buttons don't show up and when I click on the button for the 1st option, which is still visible, it shows the price for the 2nd option. I noticed the subscription product setup asks for a url for the product. Can you only have one product subscription per page? Is that what is causing this?
