popUpWindow - scrollbar calling problem

[donna karan]

Hello again.
Solving aditional problem, please help.
Everything working all right in IE, but Netscape does not shows scrollbar. It is possible to scroll the popUp window with mouse wheel, but there is not the bar :-(
Thank you!

scrollbar (beginning) X scrollbars (parameters).
It needs just to rewrite scrollbar to scrollbars, that´s all.
Have a nice time!
