Hey guys,
Sorry if this is been answered 1000 times before but I keep getting this message whenever I test my movie… I’ve googled it so many times and I still can’t figure it out.
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Main()
at site()
at flashsitecopy_fla::wholeSite_1/frame1()
I’ve used a tutorial on dynamic websites and another tutorial from Computer Arts magazine.
Main is an external Base class file
and site is the movie clip I’m trying to add to my website
This is from Main.as

if you could tell me what I’m doing wrong or how to fix it that would be awesome.
