I asked Thom why this link wasn't working properly, why it resulted in an error page at Paypal. He suggested it was because there was an extraneous dollar sign in the tag for Total Due. I removed that extra $ and the link seems to work now. However, when placed in the footer section of an email template, that tag still displays wrong -- it shows the actual dollar amount in the email message received by the buyer, instead of just the tag. Can anyone tell me how to change this link so it will work properly in an email template? Thanks.

Here's the link (this board removes the "percent20" space filler in the Total Due tag -- not sure why that's even needed; seems to work the same with or without it):
