I'm using rollover images on my Web site, which I designed using a very resourceful link http://www.redbooks.ibm.com/tstudio/domino/store/b2b2/rollover.htm...
I noticed that the rollovers work very well once the buttons are loaded on the page. However, I received very cryptic messages when I tried hovering the mouse over the buttons before they loaded on the page. Message reads as follows:
"A runtime error has occurred. Do you wish to debug?
'Well.1' is null or not an object"
How could I get rid of this problem?
