Hi all, I am having a problem for frame accessing. Below is the structure for my frameset: lesson_f ______nav ______mainpage which nav and mainpage are reside under lesson_f. I have a submit button at nav frame and via this onclick function at this submit button, it need to travel from nav frame to mainpage frame. The path should be: parent.mainpage , is this correct? After that I would like to apply scrollTo function to this mainpage frame, parent.mainpage.scrollTo(5000,0) But, it doesn't work in Firefox. Anybody can share yours idea about this? Thanks.
