As I've mentioned before, I use Microsoft Word to maintain the web site for a non-profit. To dip my toes into the waters of PayPal, I decided to go with the simplest option of adding "Buy Now" buttons to the site. To reduce concerns about people tweaking the information sent to PayPal, I decided to take advantage of PayPal's encyption option. I found that if I pasted the block of code from PayPal into the HTML editing window of Microsoft Word, Word would corrupt the block of code.
