Help creating a recurring donation button

[teenwent11]

I'm trying to create a recurring monthly donation button with preset amounts of $10, $25, $50, $100, $200. I've embedded this button into a squarespace site, but clicking produces an error. I followed this guide to create it:

https://www.paypal.com/webapps/mpp/get-started/create-recurring-donation-button#step-18

I want it to be monthly (user can't change or see)

It shouldn't end (user can't change or see)

It should only have the previous dollar amounts to choose from.

I'm not a coder and I'm not sure how to modify this code to display what I want it to. Any help would be much appreciated!

Here you go, give this one a try. You will need to put in your PayPal account email address in the business variable value, marked "<TODO>" below.
