Editor in Custom fields doesnt pass HTML

[ultimamedia]

hello, i want to pass html and javascript values through the editor editor custom field type - once i put them into the custom field, when they pass through all my html/javascript gets stripped - anyway to fix this, i want values to be done at custom fields stage not at product stage, as there is too many products.
many thanks,
Chris

There's a thread on forum about adding HTML/javascript to product description/image.

What kind of code you need to attach and why you need attach it to custom fields?

Maybe link to an example?
