Sorry to bother you guys with a noob problem like this.
Apparently, Adobe Flash CS3 is telling me that the package I defined "does not reflect the location of the file". RRRRRRRRRage
The program consists of two parts, an .fla, and an .as, which are located in a folder named ListenerTest, which is in turn, located in Exp, located in Flash, located on my C:.
Both files are located in: (C:/Flash/Exp/ListenerTest)
What should I name my package so that this error doesn't show up?
