For some reason that I don't yet understand, the following code gives me this error -- "Uncaught TypeError: Cannot read property '0' of undefined" However, when I use that array elsewhere in my code, I don;t get the error. Can anyone clue me in on what's going wrong? -=-=- Check out my excellent homepage!

Do you try to read from items[0] elsewhere?

Will a test for items[0]==1 throw up a flag if items[0] is undefined? It may just say, nope, not equal to one and continue.

Here's a crazy solution, if I put
into a different file (levels.js) everything works fine. That makes no sense to me at all. -=-=- Check out my excellent homepage!

I can't see anything obviously out of place... I guess you may have already tried this, but what happens if you replace the parameters of strokeText and fillText with (hardcoded) the values that might be stored in your array? Just to double-check the exact location of the problem. Could the '0' not be one of the values stored in the array rather than the subscript of the array cell?

What if you replace "var items =" with "window.items ="? Does it work then? Perhaps you can create a proper global variable that way.
