One short question:

[allegrande]

form name is: BreedRegist
(hidden)field name is: lng

Is this the rigth way to receive values from a another window (called kart.html)

in kart.html I have this:
window.opener.document.BreedRegist.lng.value = something;

But I get this error:
window.opener.document.BreedRegist has no properties
