input text file html

I have my data in a text file delimited by tabs One field contains : <a href="#" onclick="window.open('https://www.paypal.com/cart/add=1&business=xxxx%xxxx.net&item_name=xx+xx+xx&item_number=85&amount=4.95','cartwin','width=600,height= 400,scrollbars,location,resizable,status');"><img src="http://images.paypal.com/images/xx-xx-xx.gif" border="0"></a>\ ..to be printf()'d into the resulting output html file. This one field gives me a "printf(): too few arguments" error. I am unable to look at what the htmlentities() has done with the special characters because it won't print! This was supposed to be an easy shortcut before learning mysql but... Thanks for any help niels
