at this link: dl.dropboxusercontent.com/u/4395035/vihrea.pdf screenshoot of my big problem!

pag 1: from backend: category is "nuova immagine" for which associated extra field group is "width"

pag 2: from backend: extra field is "width", in the homonymous group "width".
now that field is the only one in that group

pag 3: from backend: item is "imfreenow", extra field width is set to "width4"

pagg 4,5: from backend: menu item is "home"

pag 6: from frontend: home page result: nice!

pag 7: from backend: i add extra field "descrizione" to the width group

pag 8: from backend: i fill extra field descrizione text area with "prova!" or whatever...

pag 9: from frontend: here's the result: imfreenow image shrinks.

i need many extra field for that category, i started to work on submit form etc... but i don't want to "sacrifice" the home page!!!

any help, suggestion???
