I know it's kind of weird that I followed someone else's documentation, but it's because I know him, and he was helping me at the time :)
I don't understand what you mean with the "Title of the multi-select component selects"...how can I see if the title is in English or Norwegian? The only thin I can find is, FieldName, FieldInternalName and FieldType. And there doesn't seem to

I made a list called Company with just one column Title. Then I made a list called Product with the title column, and a lookup column showing Company-title. In my third list I added two lookup columns to Product and Company, and added the following code
in my own NewForm.aspx under ContentPlaceHolderId="PlaceHolderMain":
Can you see anything wrong with my code?
In the third list, when you can only choose one product, it works just fine. It shows the Products only after you've chosen Company. If I allow multiple selects on the Products column, I get the following error:
"Error in function: SPServices.SPCascadeDropDowns
Parameter: childColumn: Product
Message: Column not found on page"
