AS3 Error #1010

[Cboyd71]

I am currently getting an error in my code and I'm not sure why.

Here's the error:

TypeError: Error #1010: A term is undefined and has no properties.

Try commenting out sections of code until you can narrow down where the error comes from.

[kglad]

or click file>publish settings>tick 'permit debugging'>retest.

the problematic line number (ie, the one trying to reference an undefined object) will be in the (more verbose) error message.
