Scrolling text problems with css 1120: Access of undefined property.

[digitalnamo]

ok 3 errors!
news_txt.styleSheet = style; 1120: Access of undefined property news_txt
news_txt.styleSheet = style; 1120: Access of undefined property news_txt
maxScroll = minScroll - news_mc.height + mask_mc.height;


Everything is named correctly but I think it is the external stylesheet that is causing some confusion. I copied the code from a Lynda.com tutorial which worked but I added css to the mix
