Looping though multiple fields - misnamed as [Javascript] Named Layers in IE

[javascript@xxxxxxxxxx (Lau)]

Thanks Tom,

Unfortunately this script doesn't handle the cases where the number of fields in 0 or 1.
I can add in the convoluted extra bits to handle these cases but I'm hoping there's another way.
I vaguely remmember reading something where they did this by looping through the collection rather
than an array.... any ideas?

Thanks
Lau
