How to properly count lister size?

Hi, I tried to parse out some website and wanted to display links together with description and image in a list. However, - I am encountering some problems using 'supply. ... btw: lists are the most difficult part of /View to understand. It's mixed with listers and one has to know inners of /View face interface. The worst and the least intuitive part is 'supply itself. Where does the 'count come from etc etc ... So, let's say my list size is 500x400. I have 80 pixels wide rows: seznam: list 580x400 [ across ; img: image 100x100 film: text 200x15 font [color: 1.1.251 shadow: none image: none] [print film/text] ; at 101x16 desc: text 400x80 font [size: 10 color: 1.1.1 shadow: none] ] supply [ count: count + num either (count <= length? titles) [ film/text: pick titles count ; img/image: load pick images count desc/text: pick descriptions count ][ film/text: copy "" ;img/image: none desc/text: copy "" ] ] at 610x50 lista: slider 16x400 length? titles [print lista/data num: lista/data - 1 show seznam] So, length? titles returns 21. Once I scroll to the bottom of the slider, it shows some binary??? strings ... Note: descriptions string are large and don't fit in the 80 pixels wide rows ... How to properly set slider size, please? Thanks, -pekr-
