[Javascript] Popup window stumper

Terry,

	Do you have error messages turned on?  It seems like you should be getting
*something* if you're trying to call a function that can't be found.  Try
adding an alert to the beginning of the TryItOut function to see if it's
getting called; if it's not, I'd venture a guess that you still can't call
functions from other windows...

Cheers,

Peter

|Could somebody tell me why the following code doesn't work.  This file
|is included as a .js file in the head of the main document. A simple
|click on a link calls function gologit.  This function correctly
|makes a new window and displays the form and image in it, but clicking
|on the "Log In" button does nothing at all.  I'm assuming I have
|some sort of reference problem and/or confusion between the
|parent and child windows, but I am stumped!
|
|Thanks in advance.
