[Zope] VERY Confused!

[Ben Ocean]

That is some pretty funky code, Seb, but it worked! Would you *please* 
explain what you did? Especially the syntax with all the wild punctuation! 
The idea of this, my first external method, was to keep_it_simple. So much 
for that. Here's the line that worked:

<span class="top"><img src="images/top" width=<dtml-var 
"sizeCalc(1008,sizer(_.None,_))"> height=<dtml-var 
"sizeCalc(82,sizer(_.None,_))">></span>

Thanks for your help!
