Hi everyone,
Why doesn't this work? I hesitate to ask because I'm sure it's a simple answer. It's a DTML Method in the / folder. The button image is also in /.

What happens when you call an image (like <dtml-var acroread_button> does), Zope will insert a complete image tag for you: <img src="/acroread_button" width=xx height=xx alt="title of the acroread_button object"> Because you insert this inside another IMG tag, you end up with the following: <center> <a href="http://www.adobe.com/prodindex/acrobat/readstep.html"><img border=0 src="<img src="/acroread_button" height=xx width=xx alt="title of the acroread_button object">"></a> </center> which makes no sense to your browser. You want to do one of the following: <center> <a href="http://www.adobe.com/prodindex/acrobat/readstep.html"><img border=0 src="<dtml-var "acroread_button.absolute_url()">"></a> </center> which inserts the URL of the image object, or: <center> <a href="http://www.adobe.com/prodindex/acrobat/readstep.html"> <dtml-var acroread_button></a> </center> which inserts the whole IMG tag, including width and height, but you'd be missing your 'border=0' and have an alt attribute extra. The following code will insert an IMG tag with 'border=0', and without the alt attribute: <center> <a href="http://www.adobe.com/prodindex/acrobat/readstep.html"> <dtml-var "acroread_button.tag(alt='', border=0)"></a> </center> -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | T: +31 35 7502100 F: +31 35 7502111 | mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ---------------------------------------------
