That's because when you simply declare
var test:testClass;
the variable 'test' is automatically assigned a default value of null.
The default value of a var depends on its type, as follows:
Boolean --> false
int/uint --> 0
Number --> NaN
Object --> undefined
All other types --> null

Hi,
you need to create an instance of the testClass like this
var test:testClass = new testClass();
regards,
Christophe

This compiles but when you hit the test button, it says
TypeError: Error #1009: Cannot access a property or method of a
null
object reference.
at Main/test()
at Main/__b1_click()
Can anyone explain what this means ? It totally does not make
any sense
to me.
