Sorry nesi, this ones' beyond me, it's possible to do this using vba, problem is I don't know how to read Hebrew, starting from scratch this is a rather large request imo, and if you're looking for porition to portion comparison it'd be even trickier
loop through cells
submit search page
select result and navigate
change portion size (that's what I'm assuming that drop down is) to predefined values (as I'm assuming you want the values to be comparable?)
I'd recommend you look into selenium wrapper or winhttp, automation via internetexplorer is an option also, though not as stable imo.
