Controlling frame elements from another frame.

[Edge30]

Hello
I need to fill up forms online, but the format is not friendly. So I'd like
to make my own interface to fill those forms.
I made a framset with frames A and B. Frame A has my own interface with
buttoms, radiobuttons, and so on... Frame B loads the real online form. Then
by using from frame a: parent.b.document.all.elementname.value (where
elementname is an element in frame B) I pretend to control elements on frame
b.
Now
It works perfect on my PC, when the documents of frame A and B are on my PC.
But when I go online I got problems....
First I received a message "access denied" and somehow I found on the web
that the reason is that my frameset and frame A are on my PC while frame B
is on a web server.
So I moved my framset and frame A to a web server (personal one) while frame
B is still on my employeer's web server.
Now I don't receive the error (access denied) but the scripts don't work,
they just don't do anything.... no error messages.
1. did anybody understood my poor explanation?
2. does anybody know how can I solve this??
Basically I want to be able to fill a web form, but instead of typing on
that form, type on a different web page and then copy over the data to the
original form.
Hope somebody could give me a hand
Thanks

Pd. I'm not a professional programmer, but I managed to make it work perfect
on MY pc.
Thanks
