Little menu problem

I have a problem building a menu with flash. I am using the following code on a button:

on (release) {

It keeps saying that it cannot find the path to the appropriate folder.

I have tried inserting an internet address and it works, but when it is a local path it won’t recognize it.

Here is a little more information about the menu:

I built it using 5 frames. When you hover over the button it takes you to a different frame which alters the design. I have set the above code on the frame on which the user clicks.

Please ask any questions if something is unclear.

Thank you
