Actually, what I was trying do say (and didn't say very well) is that I don't see what you're actually trying to accomplish with your foreach() loop. Unless you *use* the result of each iteration through the loop within the body of the loop (print it, store it to some other structure, etc.), all you're really doing is assigning $val (or $a, in your modified example) based on the *last* element in your array. Mike P.S. I believe Pete correctly identified the cause of your error message.
