Compile error, type not found

Hi,

I am an actionscript newbie, and I am trying to do something seemingly simple.

I have an actionscript file with a class defined, and I am trying to define an object for that class in another actionscript file but I keep getting a compile error that says type not found.

Here is what my code looks like

ABC.as

package{

public class ABC{



}

Paint.as

import ABC

package{

public class Paint extends Movieclip{

[COLOR="Red"]var abc:ABC;  // throws an error [/COLOR]

}

}

If someone could point me in the right direction that would be great.

Thank you,
Amrita
