How do I use achor text to send people to my Paypal order page? For example: "Click Here To Order Now".

My Paypal buttons are working fine but when I link my order page up to anchor text it works for a day but the next day it doesn't. I think it's because Paypal is so secure that it changes the order url everyday.

Can someone please advise me on this issue? Thanks in advance.
