submitting two frames from one frame

[HobbyMan]

I have a frameset with two frames. Both the frames have
forms. What I wish to do is have the top form have one
button that submits both frames. Is that possible? And how?

I had the idea that the top window, from javascript, would
submit the bottom frame, check for the existence of a
variable in the bottom frame and on that finding submit the
top frame. I set a timer to keep checking until it is found.

I have read that to check for the existence of a variable
you simply do this:
if ( window.variablename )
alert("variable exists&quot
else
alert("variable does not exist&quot

When doing this I get the error "object is null or does
not exist" (javascript error dialog).

Does anybody have a good idea on this?

You reference objects in frames slightly different. Here is the method that I use.

top.framename.variable

The same applies for the forms.

top.framename.formname.submit();

will submit the form formname in the frame framename.

How do you submit the two frames?

If I have

top.FRAME1.forms[0].submit();
top.FRAME2.forms[0].submit();

it works fine under IE 6 but under NS 4 and Mozilla FRAME1
is the only one that gets submitted.

Hmm, I don't and never have written for NS4, so I'm not sure.
Try parent.frames[1].forms[0].submit();

Don't forget frames are numbered from 0 too.
